Which of the following cations does not form complex with ammonia?

A

`Cd^(2+)`

B

`Pb^(2+)`

C

`Ag^(+)`

D

`Cu^(2+)`

Text Solution

Verified by Experts

The correct Answer is:
2
Ammonia is Lewis base. It forms complexes with cations but fails to form complexes with `Pb^(2+)` ions because it lacks empty d-orbitals and has low charge density.
