1.	Which one of the following undergoes nitration most readily ?
Answer» Acetophenone Benzonitrile Benzaldehyde benzene Solution :Acetophenone, benzonitrile, benzaldehyde and benzoic acid all contain ELECTRON-withdrawing GROUPS, therefore, in all these compounds the electron density over the phenyl ring is LOWER than in benzene. Thus, benzene UNDERGOES electrophilic nitration most READILY.
