When excess of ammonia is added to `CuSO_4` solution, the deep blue coloured complex is formed. Complex is

A

tetrahedral and paramagnetic

B

tetrahedral and diamagnetic

C

square planar and diamagnetic

D

square planar and paramagnetic

Text Solution

Verified by Experts

The correct Answer is:
D
`[Cu(NH_3)_4]^(2+)` is the complex with deep blue colouration. It is square planar `(dsp^(2)` hybridised ) and paramagnetic. For detials , consult section 9.10
