Which has the highest pK(b) value?...

Which has the highest `pK_(b)` value?

A

`R_(3)C-NH_(2)`

B

`R_(2)NH`

C

`RNH_(2)`

D

`NH_(3)`

Text Solution

Verified by Experts

The correct Answer is:
D
Higher the basicity, higher is the `K_(b)` value and lower is the `pK_(b)` value. Here `NH_(3)` is the weakest base, hence it has highest `pK_(b)` value.
