Sample questions

1. 1.Why are diazonium salts of aromatic amines more stable than those of aliphatic amines?
   • A.The arenediazonium ion is stabilised by resonance with the benzene ring
   • B.Aliphatic diazonium ions are stabilised by hydrogen bonding
   • C.Aromatic amines have a lower molar mass
   • D.Aliphatic diazonium salts are aromatic
2. 2.Amines behave as bases because of the:
   • A.Unshared pair of electrons on the nitrogen atom
   • B.Presence of an acidic N-H bond
   • C.High electronegativity of hydrogen
   • D.Empty d orbitals on nitrogen
3. 3.In the Hoffmann bromamide degradation reaction, an amide is treated with bromine in aqueous or ethanolic NaOH. The primary amine formed:
   • A.Contains one carbon less than the starting amide
   • B.Contains one carbon more than the starting amide
   • C.Contains the same number of carbons as the amide
   • D.Is always an aromatic amine
4. 4.Aromatic primary amines react with nitrous acid at low temperature (273-278 K) to form:
   • A.Diazonium salts
   • B.Alcohols and nitrogen
   • C.Nitro compounds
   • D.Amides
5. 5.Aromatic amines such as aniline are weaker bases than ammonia because:
   • A.The nitrogen lone pair is delocalised into the benzene ring by resonance
   • B.The amino group has a strong +I effect
   • C.Aniline cannot form an anilinium ion
   • D.The benzene ring donates electrons to nitrogen
