Correct answer
CVCl4

Step-by-step explanation

Spin only Magnetic Moment

μ = n n + 2  BM = 1 . 7 3 = 3

∴  n = 1     (unpaired e-)

Electronic configuration of V= 1s 2 2s 2 2p 6 3s 2 3p 6 3d 3 4s 2



to get 1 unpaired electron V has to lose 4 electrons to form V 4+.

So, formula of chloride is VCl 4
