Tertiary nitro compounds cannot show tautomerism because:
1. they are very stable
2. isomerises to give sec. nitro compounds
3. do not have labile H-atom
4. they are highly eactive
A secondary amine is:
1. a compound with two -NH2 groups
2. a compound with 2 carbon atoms and a -NH2 group
3. a compound with a -NH2 group on the carbon atom in number 2 position
4. a compound in which 2 of the hydrogens of NH3 have been replaced by alkyl or aryl groups
An amine gives a solid compound that is insoluble in alkali with benzene sulphonyl chloride.

Ethylamine and diethylamine cannot be differentiated by:
(1) Hinsberg test
(2) carbylamine test
(3) Iodoform test

Hinsberg's method to separate amines is based on the use of:
(1) benzene sulphonyl chloride
(2) benzene sulphonic acid
(3) ethyl oxalate
(4) acetyl chloride
A primary amine heated with CS2 in presence of excess of HgCl2 gives isothiocyanate. The reaction is called:
