Solution

The correct option is C Assertion is correct but Reason is incorrect
Alkyl isocyanide can be prepared by carbylamine reaction. In the carbylamine reaction (also known as the Hofmann isocyanide synthesis) potassium hydroxide reacts with chloroform to produce dichlorocarbene. This then converts primary amines to isocyanides. As it is only effective for primary amines, it is used as a chemical test for their presence.
