For which of the following pairs, magnetic moment is same ?

Options

A. `MnCl_(2),CuSo_(4)`
B. `CuCl_(2),TiCl_(3)`
C. `TiO_(2),CuSO(4)`
D. `TiCl_(3) NiCl_(2)`

Answer

B

Explanation

Species having the same number of unpaired electronic, have same magnetic moment.
`CuCl_(2)impliesCu^(2+)=[Ar]3d^(9),4s^(0)` (one unpaired electrons)
`TiClimpliesTi^(3+)=[Ar]3d^(1),4s` (one unpaired electron) ,
`:.CuCl^(92) and TiCl_(3)` have same magnetic moment.
`mu=sqrt(n(n+2))=sqrt24BM`
