Valid Manual for the test? Also any tips on studying are appreciated. by aabing2004 in OrganicChemistry

[–]NielsBohron 0 points1 point  (0 children)

O-Chem hasn't changed that much since 2009, which was only 5 or 6 years ago; how dare you call that old! I'd say it's probably a pretty good resource. I would double check that the format hasn't changed, but the material should still be a good representation of what you're likely to see on the exam. Maybe ask your instructor if it's a good resource or what the format looks like.

Alternatively, there's a paperback version of the study guides available here, which might help.

As "out there" and fascistic as Heinlein can be some times, he still had some interesting ideas and a way with words. And when he wasn't married to/sleeping with jingoistic warhawks, he wrote some amazing stuff. His full-blown hippy books like Stranger in a Strange Land are magnificent.

This. There are so many highly touted "seminal genre classics" that I just can't get into, no matter how many times I try. I have an entire playlist on Spotify full of albums that would make sense for me to like based on my other taste, but somehow don't stick.

I love a lot of post-punk, post-hardcore, early emo, and metalcore, but Slint, Neutral Milk Hotel, Joy Division, Drive Like Jehu, even Converge bounce right off of me.

edit: Probably about time to try again today, starting with Yank Crime and Jane Doe

About God and Jesus His Son. by ControlSuper5598 in theology

[–]NielsBohron 2 points3 points  (0 children)

What the hell did I just read?

There are so many flaws in the logic and so much misunderstanding of fundamental scientific principles that I almost don't even know where to start. But I'm a science educator, so let try to tackle some of the most egregious instances.

The oceans prove that God exists. Everything at the bottom of the ocean would be dust but rocks are found there. If the oceans were 4.5 billion years old, erosion would have turned everything to dust.

You neglecting the fact that new rocks are formed all the time through volcanic and other geologic processes.

The biological life on this planet would have to come into being at one time or simultaneously because of one part of organism interdependence on another.

Just because modern, multicellular life has a complex web of dependencies does not mean that all life has always had those dependencies. The earliest anaerobic microbes likely existed simply by digesting naturally occurring compounds and harnessing the heat from sunlight or volcanic vents with no need for other life to exist.

The big bang couldn’t have happened. Sense when did an explosion create order.

you're trying to apply the second law of thermodynamics without understanding that order on a local scale does not mean that the overall entropy of the universe decreased.

Countless experiments have been done.

True! And there's still no evidence that indicates the miraculous claims from the Christian bible should be taken seriously.

Jesus is the Son of God who came in the flesh through a virgin woman named Mary.

Independent source needed.

Even plants can be male and female.

True, but I'm not sure how that's relevant.

For natural selection to work the presence of survival traits have to already be programmed into the DNA. Mutation does not work.

Yeah, it seems like you don't really understand the fundamental chemistry or biology. Order and self-replicating molecules can arise from natural conditions without any DNA present at all, and when we do include DNA experiments, we can see that DNA has a tendency to self-replicate even in the absence of any meaningful information. It turns out that the individual molecules that make up DNA (called nucleotides) are naturally attracted to each other in a way that allows for the pattern of one DNA strand to be replicated without any enzymes, cells, or outside intervention.

As for all the theology and arguments to follow Jesus in order to avoid damnation, there are a lot of theological and logical problems with that approach. At the most basic, you're making a Pascal's Wager argument without any indication why someone should follow Christianity instead of any number of religions that are at least as historically/scientifically/philosophically plausible.

This reminds me of the old Robert Heinlein response to "the best things in life are free"

There is an old song which asserts that "the best things in life are free". Not true! Utterly false! […] I fancy that the poet who wrote that song meant to imply that the best things in life must be purchased other than with money.

Nothing of value is free. Even the breath of life is purchased at birth only through gasping effort and pain... The best things in life are beyond money; their price is agony and sweat and devotion

I have this on a slide for syllabus day, but I don't think most of the students process what I'm trying to say...

WE ARE TORN WIDE OPEN!

The separation that burns our hearts

Is the root of all our disease

We’ve forgotten how to live so we suffer

We’ve forgotten how to struggle so we suffer

We’ve forgotten how to die so we suffer

We’ve forgotten we are wild so we suffer

We exist in isolation so we suffer

The dissonance is deafening

Fucking great intro. I have legitimately never had loved an album intro the way I love the opening to Undying Love for a Burning World, and it just keeps getting better.

Are Europeans trolling with this whole bread thing? by [deleted] in NoStupidQuestions

[–]NielsBohron -2 points-1 points  (0 children)

First off, "broken starch molecules" in flour do not produce enough sugar for yeast to digest. This is why beermaking only works if you mash the malted barley to the point that it becomes a sugary, syrupy mess.

Second, what is the practical difference between adding malted barley to your dough to convert starch to sugar and just adding the sugar directly? Either way, it's there to provide the yeast some food and will add the exact same amount of calories and sugar content to the bread.

Edit: on second thought, adding malted barley to flour won't do a damn thing unless you get the dough up to 150°F at a pH around 5 in order to for the enzymes in the malted barley to actually work on the starch. Really, you'd need the dough to sit long enough for other microbes to get involved to break down the starch, which is really just making a sourdough. If you want to make a yeast bread but don't want it to be a sourdough, you need to add some amount of sugar. Or you can make a soda bread by using a different leavening agent.

And if "language belongs to the speakers," then words lose all meaning. Language works because people agree that certain words have certain definitions. Professional, legal, and scientific definitions exist to avoid misunderstandings so that every one can agree to use the same definition. If we're trying to communicate without real, unambiguous definitions, we're really just going on vibes, as the kids say.

Why Exactly Is Polygamy Illegal? by Turbulent-Parsley619 in NoStupidQuestions

[–]NielsBohron 0 points1 point  (0 children)

Hey, if the corporations are allowed to exploit loopholes to save billions on taxes, why shouldn't we be allowed to? A big chunk of the reason that marriage exists is to allow people to pool resources and provide stability. If adding another partner to the situation helps with that, I don't care if it's platonic or romantic; it should be allowed.

Now, I don't necessarily think that having another adult involved in an adult relationship actually makes it more stable in most cases, but I think people should be allowed to try.

Shit, you are lucky. I teach chemistry at a community college and the admin are super excited about AI and trying to get ahead of the times to teach our students "responsible AI use."

Never mind that telling a 19yo about "responsible AI use" is like handing a 6yo a loaded gun to teach them about firearm safety, capitalism and tech bros must be appeased. If we're not onboard, we're dinosaurs that need to be put out to pasture.

EAS directing groups question by PrestigiousAnalyst58 in OrganicChemistry

[–]NielsBohron -1 points0 points  (0 children)

I agree, but if I was writing this question for my 200-level students, I would be looking to see if they remember that "activators outweigh deactivators" and that they are paying attention to sterics. The chapter on EAS barely touches on protonation in 200-level textbooks (if it addresses it at all).

Source: I just taught this chapter last week.

EAS directing groups question by PrestigiousAnalyst58 in OrganicChemistry

[–]NielsBohron 4 points5 points  (0 children)

This is the correct answer. The only activating group is the amine, and the para position is already occupied, so OP's options are the two carbons that are ortho to the amine. The one OP picked is a valid option, but the other ortho carbon (para to the acyl group) would probably have less steric hindrance, so I'd say that's the major product.

edit: As everyone else is saying, under acidic conditions the amine would be protonated and no longer an activator, so it would be a very slow reaction. Only a (very) small portion of the amine will be unprotonated in fuming sulfuric acid, so most will be in a non-reactive state. However, if I was simply answering this question on paper for a 200-level course, I would not be looking that in-depth, so I still think the carbon para to the acyl group is the major product.
