MolSynapse / Question bank / Organic Reaction Mechanisms II: Electrophilic and Radical Reactions / Electrophilic aromatic substitution: mechanism and directing effects

NEET levelSingle correct optionDifficulty 1 of 3o2118

Friedel-Crafts alkylation fails with

Atoluene
Banisole
Cbenzene
Dnitrobenzene

Answer: D

The strongly deactivating

- NO X_{2}

group makes the ring too electron-poor to attack the carbocation-like electrophile. Benzene, toluene and anisole are not deactivated, so they react.
