The spin-only magnetic moment value of the most basic oxide of vanadium among \(V _{2} O _{3}, V _{2} O _{4}\) and \(V _{2} O _{5}\) is \(.....\,B.M.\) (Nearest Integer)
- A \(3\)
- B \(30\)
- C \(0.3\)
- D \(56\)
Answer & Solution
Correct Answer
(A) \(3\)
Step-by-step Solution
Detailed explanation
Most basic oxide is \(V _{2} O _{3}\) \(V ^{+3} \rightarrow\left[A_{ r }\right] 3 d ^{2}\) \(\mu=\sqrt{2(2+2)}=2.84\, BM\) \(\approx 3\)
