A
Correct Answer
B
Correct Answer
C
Correct Answer
DNone of these

Solution

In $$SN_2$$ reaction, the nucleophile attacks at the carbon with the partial positive charge. The Carbon with more positive charge is more reactive towards the $$SN_2$$ reaction.

A. In $$CH_3COCl$$, the $$C$$ of carbonyl is more positive than the $$C$$ in $$CH_3Cl$$.

B. The $$C$$ of $$CO$$ group of $$C_6H_5-CONH_2$$ has defined positive charge than in aniline.

C. Both the $$C$$ of $$CO$$ are more positive and highly reactive than $$CH_3OCH_3$$.
