In chromyl chloride, the number of d-electrons present on chromium is same as in (Given at no. of \(Ti : 22, V : 23, Cr : 24, Mn : 25, Fe : 26)\)
- A \(T_i\,(III)\)
- B \(Fe\, (III)\)
- C \(V\, (IV)\)
- D \(Mn\,(VII)\)
Answer & Solution
Correct Answer
(D) \(Mn\,(VII)\)
Step-by-step Solution
Detailed explanation
In \(CrO _2 Cl _2\) oxidation state of \(Cr\) is +6 \(Cr ( VI )=[ Ar ]^{18} 3 d ^0\) \(Mn ( VII )=[ Ar ]^{18} 3 d ^0\) \(Fe ( III )=[ Ar ]^{18} 3 d ^5\) \(Ti ( III )=[ Ar ]^{18} 3 d ^1\) \(V ( IV )=[ Ar ]^{18} 3 d ^1\) Hence \(Cr\) (VI) and \(Mn\) (VII) have same \(d^0\)…
