Assertion. Both [Ni(CN)_(4)]^(2-) and [NiCl_(4)]^(2-) have same shape and same magnetic behaviour. Reason. Both are square planar and diamagnetic.

Answer»

If both assertion and reason are true, but reason is not the true EXPLANATION of the assertion
If both assertion and reason are true, but reason is not the true explanation of the assertion
If assertionis true, but reason is false
If both assertion and reason are false

Solution :Correct A. `[NI(CN)_(4)]^(2-)` is square planar and diamagnetic WHEREAS `[NiCl_(4)]^(2-)` is TETRAHEDRAL and PARAMAGNETIC.
Correct R. `[Ni(CN)_(4)]^(2-)` is tetrahedral.
