(a) Illustrate Sandmeyer's reaction with an equation.
(b) Explain, why

({CH}_3)_2 {NH}

is more basic than

({CH}_3)_3 {N}

in aqueous solution.

Solution:

(a) Sand meyer's Reaction -

(b) The order of basicity is

({CH}_3)_2-{N}>({CH}_3)_3-{N}

because alkyl group is small, there is no steric hindrance to

{H}

-bonding, So, nature of alkyl group is responsible for basicity of

2^0
