Magnetic moment of [ Ti ( H ₂ O )₆ ]⁴⁺ , [ Mn ( H ₂ O )₆ ]²⁺ and [ Cr ( H ₂ O )₆ ]³⁺ can be represented as X, Y and Z . They are in order of
Options
- AX Z Y
- BZ Y X
- CX Y Z
- DZ Y X
Correct answer
A. X Z Y
Step-by-step solution
aligned X =[ Ti & . ( H ₂ O )₆ ]⁴⁺, E C of Ti ⁴⁺=3 d^ n & =0 _B & =0 Y & = [ Mn ( H ₂ O )₆ ]²⁺, E C of Mn ⁺²=3 d^5 n & =3 _B & =3.87 BM Z & = [ Cr ( H ₂ O )₆ ]³⁺, E C of Cr ³⁺=3 d^3 n & =3 _B & =3.87 BM aligned Hence, the correct order of magnetic moment of X, Y, Z is X Z Y
