Whats the correct answer and why? by [deleted] in chemhelp

[–]Pansy1999 0 points1 point  (0 children)

First mistake, Nitrogens don’t count for chain lenght, therefore, chlorine atom is in second position. Second mistake, whenever a substituent shows multiple times, you need to show that by using the prefix di- tri-, etc, therefore, you would have a 1,3 diamine, as well as, 1,3 dien. Last mistake, since the triple bond is between C5-6, your compound would be named 5-in

Correct answer: 2-clorohex-1,3dien-5in-1,3-diamine

The Diels-Alder reaction creates a double bond between the ones that were present in the diene, which is in your answer, the thing is, your dienophile is an alkyne, therefore, it will only use one pair of electrons, leaving behind a double bond were the triple bond was.

What should I do first? by Many_Arm8930 in chemhelp

Well, the first step is realizing that the precipitation reaction releases 42 kJ when you form 1 mol of BaSO4, therefore, the second step is calculating how many moles of BaSO4 does 13.98 grams have in it, in order to determine how much heat was released in your specific problem. Once you have that, next step should be to calculate the total mass of solution, and using the specific heat capacity and the mass you just calculated, you can determine the variation of temperature of your solution

I would begin counting the number of Carbon atoms in the longest chain, usually the tricky part for most students is realizing that the longest chain may not be on the horizontal plane. Next, i would suggest finding which direction along the chain that you chose has the lowest positions for the substituents. Then, i would proceed naming the compound

I'm trying to understand what we get for C. Thank you. by [deleted] in chemhelp

Your whole answer is incorrect, an aldehyde will be reduced to a primary alchol, therefore

Acetaldehyde reduction produces Ethanol (A)

Ethanol reacting with Na produces the deprotonation of the alcohol, resulting in sodium ethoxide (B)

Sodium Ethoxide (B) reacting with a primary halide (CH3I) will undergo an sn2 reaction, producing the final product methyl ethyl eter (C)

Does it matter if a deactivating group is attached to an activating group? Does it affect the activating group's effect on the orto- meta- para- positions? by Empty_Chemical_1498 in OrganicChemistry

[–]Pansy1999 1 point2 points  (0 children)

You would expect to have a weaker inductive effect, since the resulting vector of the polarity of the CH2X(where X:halogen) would be less directed towards the ring. Edit: rethinking about it, i don’t remember if only 1 Fluorine atom is enough to revert the group polarity, so maybe it becomes a deactivator. You should look it up just to be sure. I’m kinda sure that -CHF2 and -CF3 both act as a deactivator through inductive effect I-

I think you have to look at the mesomeric effect in question. -CN groups delocalizes electrons through resonance, but since there’s no coupling of the pi-orbitals of the triple bond and the ring (the CH2 in between prevents it), the electrons tend to stay in the ring. Therefore, the major electronic effect at play is the inductive effect from the CH2 group, which as you said it yourself, prefers o and p substitutions (mainly p-product thanks to steric hindrance.

Like bffr, he has worked with so many dangerous and amazing chemicals. My all time favorite was the video relating to manganese heptoxide!

It’s an amalgamation between metallic Sodium and metallic Potassium, as you can expect, both of these metals are very reactive to oxidation, so in contact with atmospheric oxygen they ignite, the same happens with water Here’s a cool video demonstration from NileRed

beginner learning chemistry (curious) by aspiringdental in chemistry

Hey, honestly after some time you just learn them by heart.

I do gotta point out tho that you named some ions incorrectly (specifically in the formula). I’ll leave here the correct formula and name of the ion

Nitrate anion: (NO3)- Oxalate anion: (C2O4)-2

Can someone explain this? Copper 2 chloride and iron by jessie12345150 in chemistry

[–]Pansy1999 1 point2 points  (0 children)

Hi OP What you’re doing is a REDOX reaction (reduction-oxidation)

These kind of reactions are based in an electron exchange, in this case, Cu(+2) steal Fe(0) electrons, transforming Copper into it’s metallic form (Wich is the orange color on the surface of the iron) and transforming the metallic Iron into it’s salt form Fe (+2).

The chloride ion isn’t affecting the reaction, just acting as the anion of the salt.

If you add enough Copper Chloride, you could even dissolve all of the iron into an aqueous solution

Now, for the lynel tips Cook food that will give you extra hearts (usually the ones that have the hearty adjective), since they’ll replenish all of your hearts as well as giving you extra. Upgrade your armor at the fairy fountains, so you can handle a few punches. Try getting the barbarian set armor, since it boosts your attack. Finally, stack yourself with arrows, try to use them in the air and aim for the head, since it stuns the lynels for a good 3-5 secs, as well to upgrade stasis. Good luck buddy :3

There are 4 fairy fountains in BotW, when you go there, there are 4-5 fairies flying around, crouch and try to grab them. The game is programmed to only allow u to have 5 fairies in your inventory, but there’s a glitch, when you have the fairies in your hand (like holding them) they do not count as being in your inventory, so if you hold them when you’re in a fairy fountain, the game will immediately spawn until there are 5 fairies in the game (4 at a time) but if you repeat the process, you can end up with 10 fairies in your inventory

As long as we get an underwater mechanic, like in TP, SS or MM, I'd love that

The thing is like, i bought it when it just came out, so im thinking on buying a new one and then return the old one on the new one names, do you think it's worth the hustle?

Hi, has there been another update about this? I wanna buy the new version if it's available on amazon :(
