Question

Draw the major neutral organic products

Answer 1

I think that the first one would be

Answer 2

Based on http://www2.chemistry.msu.edu/faculty/reusch/VirtTxtJml/addyne1.htm under Acidity of Terminal Alkynes

Answer 3

Does that make sense to you?

Answer 4

I understand the 1st one, its the second one I don't understand. I know it'll go under an elimination, because its not a primary alkyl halide

Answer 5

Well, I got a different answer than you for the first one. Which one do you think is correct?

Answer 6

yours is, i never finished the problem

Answer 7

Oh, ok. I think the second one basically does the same thing as the first.

Answer 8

Want to try to finish it based on the same idea as the first one?

Answer 9

for the second one its not a primary alkyl halide, its tertiary so im unsure how to draw the product

Answer 10

That's true. Let me look into that.

Answer 11

okay thank you!

Answer 12

Sure. :-) Apparantly, 2º and 3º-alkyl halides undergo elimination by an E2 mechanism. But I haven't been able to figure out what that means yet.

Answer 13

In the context of this problem.

Answer 14

It's basically the same thing, you end up with

Answer 15

E2 means bimolecular, where both molecules (in this case the the deprotonated alkyne and the alkylhalide) interact - opposed to an E1 mech where the Br would first leave the tertiary alkylhalide

Answer 16

that one is incorrect.

Answer 17

can you post a screen shot?

Answer 18

it's possible that you drew it wrong?

Answer 19

it wanted the starting product as well
