Question

The major products ‘P’ formed in the following sequence of reaction is

• A.
• B.
• C.
• D.

Answer 1

The Correct Option is C

To determine the major product ‘P’ from the given reaction sequence, let's analyze each step:

1. Step 1: Reaction with SOCl₂

   The reaction of the given alcohol with thionyl chloride (SOCl₂) converts the hydroxyl group (-OH) into a chloro group (-Cl) via nucleophilic substitution. This forms an acyl chloride.

   

2. Step 2: Reaction with R-NH₂

   Amines react with acyl chlorides to give amides. Thus, the product from Step 1 reacts with R-NH₂, forming an amide linkage.

3. Step 3: Reduction with LiAlH₄

   Lithium aluminium hydride (LiAlH₄) reduces amides to amines. So, the amide from Step 2 is reduced to the corresponding amine.

4. Step 4: Hydrolysis with H₃O⁺

   The final treatment with acidic water (H₃O⁺) completes the transformation, stabilizing the amine product and ensuring any intermediates are fully reacted.

The final major product ‘P’ from these steps is an amine formed through the reduction of the amide intermediate.

Upon reviewing the options, the structure matching the amine formed is shown as the correct answer.
