Chloro compound of Vanadium has only spin magnetic moment of \(1.73\, BM\). This Vanadium chloride has the formula
- A \(VCl_2\)
- B \(VCl_4\)
- C \(VCl_3\)
- D \(VCl_5\)
Answer & Solution
Correct Answer
(B) \(VCl_4\)
Step-by-step Solution
Detailed explanation
\(\mu = \sqrt {n(n + 2)} \) \(1.73 = \sqrt {n(n + 2)} \) On calculating the value of \(n\) we find \(n=1\) No. of unpaired electrons \(= 1\) hence its consfiguration will be \(V(23) = [Ar] 3d^3\,4s^2\) \(V^{4+} = [Ar]3d^1\) Its chloride has the formula \(VCl_4\)
