The Correct Option is D

Solution and Explanation

Step 1: Understand the Carbymine reaction.
The Carbymine reaction is a reaction of primary amines with chloroform (CHCl$_3$) in the presence of alcoholic KOH to form an isocyanide (carbamine).
Step 2: Analyze the options.
- Hydrolysis is the reaction of a compound with water to break it down. It does not involve chloroform. - Reduction refers to the gain of electrons or decrease in oxidation state, which is not applicable here. - Wurtz reaction involves the coupling of two alkyl halides in the presence of sodium metal and is unrelated to amines or chloroform. - Carbymine reaction is the correct reaction, as it involves the formation of an isocyanide when a primary amine reacts with chloroform and KOH.
Step 3: Apply to the options.
The correct answer is (D) Carbymine reaction.
Final Answer: \[ \boxed{\text{Carbymine reaction}} \]
