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

Explanation

(i) Aldehyde yield 4-methylpent-2-en-1-ol is,
`CH_(3)-underset(CH_(3))underset(|)(CH)-CH=CH-CHO`
(ii) Acid yield 4-methylpent-2-en-1-ol is,
`CH_(3)-underset(CH_(3))underset(|)(CH)-CH=CH-COOH`
(iii) Ester yield 4-methylpent-2-en-1-ol is,
`CH_(3)-underset(CH_(3))underset(|)(CH)-CH=CH-COOC_(2)H_(3)`
The above shown compounds udergo reduction reaction to yield 4-methylpent-2-en-1-ol.
`CH_(3)-underset(CH_(3))underset(|)(CH)-CH=CH-CH_(2)-OH`
