Question

High basicity of $M{e}_{2}NH$ relative to $M{e}_{3}N$ is attributed to :

• A. effect of solvent
• B. inductive effect of $Me$
• C. shape of $M{e}_{2}NH$
• D. shape of $M{e}_{3}N$

Answer 1

Answer: (A)

Electrons donors are bases. Greater the stabilisation of cation formed by loss of $e^{-}$ more will be basicity of amine.

$2^{\circ }$ amine is more basic than $3^{\circ }$ amine because

$2^{\circ }$ amine is stabilised by hydrogen bonding with solvent molecule.
