Text Solution

Verified by Experts

The correct Answer is:
D
When primary amines are heated with chloroform in the presence of alcoholic KOH, isocyanides are formed. This reaction is known as carbylamine reaction. e.g. ethyl amine gives ethyl isocyanide on treatment with `CHCl_(3)` and alcoholic KOH
`underset("Ethyl amine")(C_(2)H_(5)- NH_(2)) + underset("Chloroform")(CHCl_(3)) + 3KOH (alc) overset(Delta)rarr C_(2)H_(5)- N rarr = C + 3KCl + 3H_(2)O`
