Write the structure of the aldehyde, carboxylic acid and ester that yield 4-methylpent-2-en-1-ol.

Explanation

4-methylpent-2-en-1-ol.
`CH_(3)-underset(CH_(3))underset(|)CH-CH_(2)-OH`
The structure of aldehyde, carboxylic acid and ester that would yield the above compound are
(i) Aldehyde `CH_(3)-underset(CH_(3))underset(|)(CH)-CH_(2)=CH-CHO`
(ii) Acid: `CH_(3)-underset(CH_(3))underset(|)(CH)-CH_(2)=CH-COOH`
(iii) Ester:
`CH_(3) - underset(CH_(3))underset(|) CH-CH_(2)=CH-CH_(2)-COOR`
