Question

Identify the compound A and Bin following reaction.

\[\ce{CH3Cl ->[KCN(alc)][\Delta] A ->[2H2O][HCl] B + NH4Cl}\]

विकल्प

• A = Methyl cyanide, B = Methanoic acid

• A = Ethanenitrile, B = Ethanoic acid

• A - Methylisocyanide, B - Methanoic acid

• A = Ethanenitrile, B = Methanoic acid

Answer 1

A = Ethanenitrile, B = Ethanoic acid

Explanation:

\[\begin{array}{cc}
