Chapter 23: Q23E (page 783)

What ketones or aldehydes might the following enones have been prepared from by aldol reaction?

Short Answer

Expert verified

Compound (a) can be prepared by aldol reaction of pentan-3-one. Compound (b) can be prepared by aldol reaction of 3-methylbutanal.

Step by step solution

01

Aldol reaction for compound (a)

The structure of the compound (a) is,

This compound can be prepared by the aldol reaction of pentan-3-one.

Thus, 5-ethyl-4-methylhept-4-en-3-one is the aldol reaction product which results from the reaction of two molecules of petan-3-one.

02

Aldol reaction of compound (b)

The structure of compound (b) is,

This compound can be prepared by the aldol reaction of 3-methylbutanal.

Thus, 2-isopropyl-5-hex-2-enal is the aldol reaction product which results from the reaction of two molecules of 3-methylbutanal.
