An aqueous solution of titanium chloride, when subjected to magnetic measurement, measured zero magnetic moment. Assuming the octahedral complex in aqueous solution, the formulae of the complex is:
  1. $\left[\mathrm{Ti}\left(\mathrm{H}_{2} \mathrm{O}ight)_{6}ight] \mathrm{Cl}_{2}$
  2. $\left[\mathrm{Ti}\left(\mathrm{H}_{2} \mathrm{O}ight)_{6}ight] \mathrm{Cl}_{4}$
  3. $\left[\mathrm{TiCl}_{3}\left(\mathrm{H}_{2} \mathrm{O}ight)_{3}ight]$
  4. $\left[\mathrm{TiCl}_{2}\left(\mathrm{H}_{2} \mathrm{O}ight)_{4}ight]$

Solution

$\left[\mathrm{Ti}\left(\mathrm{H}_{2} \mathrm{O}ight)_{6}ight] \mathrm{Cl}_{4}$
Coordination number $6 \Rightarrow$ octahedral complex Ti is in $+4$ oxidations state $\Rightarrow$ no unpaired electrons
$\Rightarrow$ magnetic moment $=0$ B.M. ,
