An aqueous solution of titanium bromide shows zero magnetic moment. Assuming the complex as octahedral in aqueous solution, the formula of the complex is .

Options

A. `[Ti(H_(2)O)_(6)]Cl_(2)`
B. `[Ti(H_(2)O)_(6)]Cl_(4)`
C. `[TiCl_(3)(H_(2)O)_(3)]`
D. `[TiCl_(2)(H_(2)O)_(4)]`

Answer

B

Explanation

`[Ti(H_(2)O)_(6)]Cl_(4)`
Coordination number 6`implies`octahedral complex
Ti is in +4 oxidations state `implies`no unpaired electrons
`implies`magnetic moment=0 B.M.
