Choose the incorrect statement.
Primary amines show intermolecular hydrogen bonds
Tert-butylamine is a primary amine
Tertiary amines do not show intermolecular hydrogen bonds
Isopropylamine is a secondary amine
Amine that cannot be prepared by Gabriel phthalimide synthesis is

benzylamine
methylamine
iso-butylamine
The reaction of CHCl3 and alcoholic KOH with p-toluidine gives
C.
Aliphatic and aromatic primary amines on warming with CHCl3 and alcoholic KOH form isocyanide or carbylamine which has very unpleasant smell. This reaction is known as carbylamine reaction. Since p-toluidine contains an aromatic primary amine group, it undergoes similar reaction and give 4-methyl phenyl isocyanide.
The correct order of increasing basic nature of the following bases is
2 < 5 < 1 < 3 < 4
5 < 2 < 1 < 3 < 4
2 < 5 < 1 < 4 < 3
5 < 2 < 1 < 4 < 3
Choose the amide which on reduction with LiAlH4 yields a secondary amine
ethanamide
N-methylethanamide
N, N-dimethylethanamide
phenylmethanamide
Arrange the following amines in the decreasing order of their basic strength. Aniline (I), Benzylamine (II), p-toluidine (III)
I > II > III
II > III > I
III > II > I
II > I > III
