JEE Main levelSingle correct optionDifficulty 2 of 3nc153

Aniline does not undergo Friedel-Crafts alkylation or acylation because

Athe basic amino group forms a salt-like complex with $AlCl X_{3}$ , which strongly deactivates the ring
Bthe ring of aniline is deactivated by the -I effect of the amino group
Caniline is oxidised by $AlCl X_{3}$
Dthe amino group is meta-directing and blocks the ortho and para positions

Answer: A

The nitrogen lone pair coordinates to the Lewis acid AlCl3 to form a positively charged adduct. This nitrogen is strongly electron withdrawing, so the ring is deactivated and the reaction does not proceed.
