Q. No.

Given below are two statements: 

Assertion (A): [NiCl4]2− is paramagnetic while [Ni(CO)4] is diamagnetic though both are tetrahedral.
Reason (R): CO is a strong field ligand, thus pairing of electrons takes place in [Ni(CO)4].

  

1. Both (A) and (R) are True and (R) is the correct explanation of (A).
2. Both (A) and (R) are True but (R) is not the correct explanation of (A).
3. (A) is True but (R) is False.
4. (A) is False but (R) is True.
