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)
