A) alkene

B) amine

C) ketone

D) alkane

Correct Answer: C

Solution :

[c] Key Idea: The carbon which is more electrophilic in nature, loses an a -H with a base more readily.

Among the given compounds, carbonyl carbon

\[(>C=O)\] ie, ketone is more electrophilic in nature, thus loses an a- H with a base eg, in aldol condensation reaction a-hydrogen atom of aldehyde or ketone is abstracted by a strong base.
