JEE Main Chemistry question

The most stable resonance structure that explains the directing effect of –NH in aniline (toward electrophilic substitution) arises because

(A)The lone pair on nitrogen is delocalised into the ring, increasing electron density at *ortho* and *para* positionsCorrect
(B)Nitrogen withdraws electron density through induction only
(C)The ring is deactivated at all positions equally
(D)–NH has no effect on ring electron density

Answer: (A)

Solution

The nitrogen lone pair of the –NH group in aniline is conjugated into the aromatic ring, delocalising extra electron density specifically onto the *ortho* and *para*
