The magnetic moment (spin only) of [NiCl4]2– is (AIPMT 2011)

A.1.82 BM

B.5.46 BM

C.2.82 BM✓ Correct

D.1.41 BM

Explanation

In the given complex 2 Ni has 8 d configuration and it is a high spin complex. It has 2 unpaired electrons Hence, the magnetic moment will be n(n+2)= 2(2+2)=2.82BM Hence, the correct answer is option (c)
