How do you distinguish cyanides and isocyanides by hydrolysis and reducation.

Explanation

Hydrolysis : Cyanides on hydrolysis give carboxylic acids and ammmonia where as isocynanides on hydrolysis give primary amines and formic acid.
`R-CN+2H_(2)O overset(H^(+)//OH^(-)) to R-COOH+NH_(3)`
`R-CN+2H_(2)O overset(H^(+)//OH^(-)) to R-NH_(2)+HCOOH`
ii) Reduction : Reducation of nitriles give primary amines where as reduction of isocyanides yield secondary amines.
`R-CN+4(H) underset(Na .Alcohol)overset(LiA//H_(4)(or)) to R-CH_(2)-NH_(2)" ""Primary amine"`
`underset("alkyl isocyanide")(R-NC+4(H)) overset(H_(2)//Ni) to R-NH-CH_(3)" ""Secondary amine"`
