Which of the following is most basic

A

Benzamide

B

Butamine

C

Nitrobenzene

D

Benzene

Text Solution

Verified by Experts

The correct Answer is:
B
Benzamide :
Does not show basic character because lone pair on nitrogen is delocalized with the carbonyl group which makes it has available for protonation.

Butamine : `underset("(aliphatic primary amine)")(CH_(3)CH_(2)CH_(2)CH_(2)NH_(2))`
`R rarr NH_(2)`
R- group due to +I effect intensify the electron density on nitrogen. Therefore highly basic in nature.

`-NO_(2)` group (-I) effect, therefore makes the ring electron deficient. Hence, acidic in nature.
