Question

for the following molecule, choose two constitutional isomers that contain different functional groups: ch3ch2cooh . check all that apply.

Answer 1

Constitutional isomers of propanoic acid CH3CH2COOH that have different functional groups could include methyl ethyl ether and propanal, both having the molecular formula C3H6O but containing ether and aldehyde functional groups, respectively.

Step-by-step explanation:

Constitutional isomers are compounds with the same molecular formula, differing in the connectivity of their atoms, which leads to different functional groups.

The molecule given, CH3CH2COOH, is propanoic acid, which contains a carboxyl (-COOH) functional group.

Two constitutional isomers of CH3CH2COOH that contain different functional groups could be CH3OCH2CH3 (methyl ethyl ether, which is an ether) and CH3CH2CHO (propanal, which is an aldehyde).

Both have the same molecular formula C3H6O but differ in functional groups from propanoic acid and from each other.
