The product in the following reaction is
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) →
The reaction shown is the reduction of an amide (Benzamide) using Lithium Aluminium Hydride ($LiAlH_4$) followed by hydrolysis.
Reaction Analysis
Reactant: The starting material is Benzamide ($C_6H_5CONH_2$), which is a primary amide.
Reagent ($LiAlH_4$): Lithium Aluminium Hydride ($LiAlH_4$) is a powerful reducing agent.
Process: LiAlH4 reduces the carbonyl group (C=O) of the amide to a methylene bridge ($–CH_2–$), while leaving the C–N bond intact.
Product: The final product is the corresponding primary amine. When Benzamide is reduced, the product is Benzylamine (Phenylmethanamine).
The reaction is:
The Product
The product in the following reaction is Benzylamine.
