Statement 1 : Alkyl cyanide can be prepared by carbylamine reaction.
Statement 2 : Ethyl amine when heated with chloroform in presence of alcoholic KOH gives isocyanide

A

Statement 1 is True, statement 2 is True, Statement 2 is Correct explanation for Statement 1.

B

Statement 1 is True, Statement 2 is True, Statement 2 is NOT a correct explanation for Statement 1.

C

Statement 1 is True, Statement 2 is False.

D

Statement 1 is False, Statement 2 is True.

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, eg. 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(acl) overset(Delta)to C_2 H_5 - N -= C+ 3KCl+ 3H_2 O`
