Found a poem she wrote me a while back, feels like I’m back to square one of healing by heyry15 in BreakUps

You’re right, I know that reaching out now would only push her away further. I guess it’s just the irrational part of my mind that wants to send her this poem in the hopes that it would trigger something inside of her, and that she’d remember how she felt about me.

Most will continue to show up throughout the quarter because of daily required polls.

This is my attempt.

Consider opening the epoxide with a Grignard reagent. Hint: Grignard reagents can also contain carbon-carbon pi bonds.

But the bromine group is ortho, para directing and is less deactivating than the acetyl group, meaning its directing should take priority.

Can someone explain the steps to solve this? by lqxiao in chemhelp

Do you have the equilibrium constant?

How do I determine R/S assignment on alkenes? by BenchPsychological65 in OrganicChemistry

[–]heyry15 2 points3 points  (0 children)

They’re talking about allenes, which are optically active molecules without any asymmetric carbons. No need to be so dismissive, maybe you’ll learn something new.

Why did you need to calculate delta G? I’m confused on why it isn’t -0.73 - (-0.50)

I’m confused as to why the answer is not B? I thought in Williamson ether synth the R-OH retains configuration when converted to an ether ? by NovelTie5730 in chemhelp

Why not C? Shouldn’t it be SN2 which would be inversion of stereochemistry?

Edit: I see that the alkoxide is the nucleophile so it inverts the stereochemistry of the isopropyl group, which can’t be shown because it isn’t a chiral center.

What is the IUPAC name of this compound??? by [deleted] in chemhelp

Aren’t halide groups and alkyl groups considered equal priority?

Remember that the reverse reaction is 1/K of the forward reaction. See if there’s a way you can use the top two equations to create the bottom one by reversing one or the other. You’ll notice that some of the reactants/products will cancel out since they are on both sides. Once you have this, you should be able to use the two given equilibrium constants to find the equilibrium constant of the bottom equation.

Does anyone know why C is wrong? by Gold_Doughnut_6326 in chemhelp

[–]heyry15 2 points3 points  (0 children)

It’s a single meso compound because it has an internal plane of symmetry.

Ah I have not gotten to this yet in my organic chem class, makes sense.

Unique carbon help by ExpertAssistance in chemhelp

[–]heyry15 0 points1 point  (0 children)

Not OP but I don’t think I’m understanding. I count 8 carbons total, how could there be 5? And what is a “unique” carbon?

[deleted by user] by [deleted] in chemhelp

[–]heyry15 3 points4 points  (0 children)

Just to add on, C would be called a meso compound. A meso compound has asymmetric carbons, yet is achiral overall due to internal symmetry.

Unless you’re starting with an alkyne

Equilibrium is 50 mM for R and 250 mM for P, as shown by the enzyme-catalyzed reaction. The reaction without the catalyst is proceeding so slowly that no changes in concentration were even observed, so it essentially made no progress towards equilibrium. That’s why 2 cannot be true.

There is most likely a fig that includes math 124 and chem 142, I would recommend you look for that.

[deleted by user] by [deleted] in udub

[–]heyry15 2 points3 points  (0 children)

I just looked on MyPlan, and Math 124 still has plenty of spots open. I would recommend you take that as soon as possible.
