A. Phenyl methanamine B. N,N-Dimethylaniline C. N-Methylaniline D. Benzenamine Choose the correct order of basic nature of the above amines :

1. A > C > B > D
2. D > C > B > A
3. D > B > C > A
4. A > B > C > D

Correct answer: A > C > B > D

Solution

The basicity of amines is influenced by the electron-donating ability of their substituents. In this case, phenyl methanamine (A) has a strong electron-donating group, making it more basic, while benzenamine (D) has a phenyl group that withdraws electron density, reducing its basicity. Thus, the order A > C > B > D reflects the decreasing basicity due to the varying influence of the substituents.
