Question
In the following compounds, the decreasing order of basic strength will be:
✓
Answer
$\ce{(C_{2}H_5)_{2}NH > C_2H_5NH_2 > NH_3}$
Basic strength order
$\ce{(CH_3CH_2)_2NH > CH_3CH_2NH_{2 }> NH_{3}}$
$2^\circ$ amine, $1^\circ$ amine
Alkyl group shows $+I$ effect, and hence increases basicity.
