Question

aldo condensation reaction mechanism

Answer 1

Please do not comment unless you are making a serious attempt at a solution.

Answer 2

Is this the answer for (c)

Answer 3

Both (c) and (d) are base catalyzed. The mechanism is here

For (c) we have the aldehyde and it has a tertiary carbon substituent so it doesn't have any hydrogens to react. So you have to convert the other structure to aldol

Answer 4

I put the original aldehyde structure in red just so you could see where it was originally

Answer 5

(d)

Answer 6

tbh mechanisms are too detailed for me, I really hope your class doesn't require you to memorize all the mechanisms. Mechanisms are important but there are just too many reactions to know already

The way I see aldol-condensation to find the product easily is:
the carbonyl of the second structure, just connect where that O is to the alpha carbon of the first structure so you can form the alpha, beta-unsaturated aldehyde/ketone

Answer 7

Thank you c:

Answer 8

My pleasure!

Hopefully my answer was of some use :)
