Which of the following compounds undergoes oxidation to give acetic acid?

1. CH3—CH=CH—CH3
2. CH3—CH2—CH2—CH3
3. CH3—CH—CH2—CH3
4. CH3—CH2—CH=CH2

Correct answer: CH3—CH=CH—CH3

Solution

CH3—CH=CH—CH3 (option A) undergoes oxidation to give acetic acid because the double bond allows for cleavage and oxidation to form carboxylic acids. The other compounds lack the necessary functional group or structure for this reaction.

• Aldehydes are more reactive than ketones due to +I effect of CH3 group. There are two CH3 groups in acetone which reduces +ve charge density on carbon atom of carbonyl group. More hindered carbonyl group too becomes less reactive. So, in the given case CH3CHO is the right choice.
