Question

When methanamine is treated with benzoyl chloride, the major product is

• A. N-phenylethanamide
• B. N-methylbenzamide
• C. benzanilide
• D. acetophenone
• E. N-ethylethanamide

Hint:

Acid chloride + amine → amide formation (Schotten-Baumann reaction).

Answer 1

The Correct Option is B

Understanding the Concept: Amines react with acid chlorides to form amides via Schotten-Baumann reaction.

Step 1: Identify reactants.
• Methanamine: \(CH_3NH_2\)
• Benzoyl chloride: \(C_6H_5COCl\)

Step 2: Reaction mechanism.
• Nitrogen attacks carbonyl carbon
• Chlorine leaves
• Amide is formed

Step 3: Write reaction. \[ CH_3NH_2 + C_6H_5COCl \rightarrow C_6H_5CONHCH_3 + HCl \]

Step 4: Identify product. Product is: \[ \text{N-methylbenzamide} \]

Step 5: Match with options. Correct option is (B). Final Final Answer: \[ \boxed{\text{N-methylbenzamide}} \]
