Question

In basicity of aniline is weaker in comparison to that of methylamine due to
A. hyperconjugative effect of Me group of `MeNH_(2)`
B. resonance effect of phenyl group in aniline
C. lower molecular mass of methylamine as compared to that of aniline
D. resonance effect of `-NH_(2)` group in `MeNH_(2)`

Answer 1

Correct Answer - B
The lone pair of electrons of nitrogen atom in aniline takes part in resonance and thus is not available for donation to protons. Thus aniline is less basic than `CH_(3)NH_(2)` in which `CH_(3)` group exhibits +I effect
