A) Aniline is a stronger base than ethyl amine
B) Aniline is a stronger base than p-methoxyaniline
C) Aniline must be acetylated before nitration with an acid derivative
D) Aniline is soluble in an ammonium hydroxide solution
Correct Answer: C
Solution :
Basic character depends upon the availability of lone pair of electrons for donation. Aliphatic amines are generally more basic than aromatic amines because lone pair takes part in delocalisation in case of aromatic amines. Presence of electron releasing group at benzene nucleus increase the basic character of amine. Amino group activates the ring too much, so before nitration, aniline is acetylated with acid mixtures.
