favoured in
(a) (CH₃)₂C = O
(b) CH₃CH₂CHO O
(c) CH₃CHO ||
(d) CH₃— CH₂ — CH₂C— CH₃

Nucleophilic addition reaction will be most favored in (c) CH₃CHO
Explanation:
- The carbonyl compound undergoes nucleophilic reaction. It is because oxygen has more electronegativity than carbon atom. The carbon get partial positive charge and is subjected nucleophilic attack.
- Aldehyde is more reactive than ketone towards nucleophiles. Aldehyde has one alkyl group which has more electron donating effect.
- The ketone has two alkyl groups which makes it more difficult to undergo nucleophilic attack.
- Thus, the order of nucleophilic addition is:
CH₃CHO > CH₃CH₂CHO > (CH₃)₂C = O > O
║
CH₃— CH₂ — CH₂ — C — CH₃
