NEET 2025 Chemistry Amines MCQ Question
Type: MCQ-conceptual-Medium-Class 12
The correct order of decreasing basic strength of the given amines is :
A
N⁻methylaniline > benzenamine > ethanamine > N⁻ethylethanamine
B
N⁻ethylethanamine > ethanamine > benzenamine > N⁻methylaniline
C
N⁻ethylethanamine > ethanamine > N⁻methylaniline > benzenamine
D
benzenamine > ethanamine > N⁻methylaniline > N⁻ethylethanamine
Correct Answer
Option C
Detailed Explanation
The basic strength of amines is influenced by the availability of the lone pair of electrons on the nitrogen atom. Alkyl groups increase electron density on nitrogen, enhancing basicity. Thus, N⁻ethylethanamine is more basic than ethanamine, which is more basic than N⁻methylaniline, and benzenamine is the least basic.
