Given below are four statements regarding the chemistry of amines: (I) Hoffmann bromamide degradation reaction produces an amine with one carbon atom less than the parent amide. (II) Carbylamine reaction is given by both aliphatic and aromatic primary amines. (III) Reduction of alkyl isocyanides with LiAlH₄ yields primary amines. (IV) The product formed by the reaction of a secondary amine with Hinsberg's reagent is

Step-by-step solution

Statement (I) is correct: In Hoffmann bromamide degradation, the amine formed contains one carbon less than the parent amide due to the migration of an alkyl or aryl group from the carbonyl carbon to the nitrogen atom. Statement (II) is correct: Both aliphatic and aromatic primary amines on heating with chloroform and ethanolic KOH form foul-smelling isocyanides (carbylamine reaction). Statement (III) is incorrect: Reduction of alkyl isocyanides ( R-NC ) with LiAlH₄ yields secondary amines ( R-NH-CH₃ ), whereas red
