Question

What is the major product of Carbylamine reaction?

• A. Cyanide
• B. Isocyanide
• C. Nitrite
• D. Alkane

Answer 1

The Correct Option is B

The Carbylamine reaction involves the reaction of a primary amine (R-NH₂) with chloroform (CHCl₃) in the presence of a strong base (usually KOH). The reaction leads to the formation of an isocyanide (also known as isocyanate or carbylamine).

• Isocyanides (or isocyanates) have the general structure R-N=C, where the nitrogen is directly attached to a carbon atom with a double bond.

In this reaction:

• A primary amine reacts with chloroform (CHCl₃) and KOH, producing an isocyanide or carbylamine as the major product.

Thus, the major product is isocyanide (Option B).
