Which one of the following species cannot act as both Bronsted acid and base ?

A

`H_(2)O`

B

`HCO_(3)^(-)`

C

`HSO_(4)^(-)`

D

`NH_(2)^(-)`

Text Solution

Verified by Experts

The correct Answer is:
D
`NH_(2)^(-)` can accept a proton but cannot give a proton. Hence, it cannot act as both Bronsted acid and base.
