Given below are two statements; one is labelled as Assertion (A) and the other is labelled as Reason(R).
Assertion : Methyl amines react with benzoyl chloride to form N -methyl benzamide but forms salt with carboxylic acid.
Reason : Amines are base as well as nucleophile.
In the light of the above statements, choose the most appropriate answer from the options given below :
Options
- ABoth (A) and (R) are correct and (R) is the correct explanation of (A).
- BBoth (A) and (R) are correct but (R) is not the correct explanation of (A).
- C(A) is correct but (R) is not correct.
- D(A) is not correct but (R) is correct.
Correct answer
A. Both (A) and (R) are correct and (R) is the correct explanation of (A).
Step-by-step solution
Assertion (A):
Methyl amines react with benzoyl chloride to form N -methyl benzamide but form salt with carboxylic acid.
- This is correct. Methyl amines react with benzoyl chloride to form N -methylbenzamide, and they react with carboxylic acids to form ammonium salts.
Reason (R):
Amines are bases as well as nucleophiles.
- This is also correct. Amines can act as bases by accepting protons and as nucleophiles due to their lone pair of electrons.
Relationship:
The reason provided explains why methyl amines can react with both benzoyl chloride (acting as nucleophiles) and carboxylic acids (acting as bases).
Given this clarification, since the reason correctly explains the assertion:
The correct answer should indeed be: (1) Both (A) and (R) are correct and (R) is the correct explanation of (A).
