वैनेडियम का एक क्लोरो यौगिक \(1.73\; BM\) का केवल स्पिन मैग्नेटिक मोमैन्ट रखता है \(( V\) का परमाणू क्रमांक \(=23)\) इस वैनेडियम क्लोराइड का सूत्र होता है।

  1. A \(VCl_2\)
  2. B \(VCl_4\)
  3. C \(VCl_3\)
  4. D \(VCl_5\)
Verified Solution

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 \(VCl_4\)
