List of top Chemistry Questions on Aldehydes, Ketones and Carboxylic Acids asked in CUET (UG)

Read the following passage and answer the next five questions based on it.
Aldehydes are generally more reactive than ketones in nucleophilic addition reactions due to steric and electronic reasons. Sterically, the presence of two large groups in ketones hinders the attack of nucleophile to carbonyl carbon than in aldehydes. Electronically, aldehydes are more reactive than ketones because two alkyl groups reduce the electrophilicity of the carbonyl carbon more effectively than in the former

(C) (CH₃)₃
(D) (CH₃)₂CHCH₂
