A six coordinate complex of formula \( \mathrm{CrCl}_{3} \cdot 6 \mathrm{H}_{2} \mathrm{O} \) has green colour. A \( 0.1 \mathrm{M} \) solution of the
\( \mathrm{P} \) complex when treated with excess of \( \mathrm{AgNO}_{3} \) gave \( 28.7 \mathrm{~g} \) of white precipitate. The formula of

W the complex would be :
(b) \( \left[\mathrm{CrCl}\left(\mathrm{H}_{2} \mathrm{O}\right)_{5}\right] \mathrm{Cl}_{2} \cdot \mathrm{H}_{2} \mathrm{O} \)
(a) \( \left.\left[\mathrm{Cr}\left(\mathrm{H}_{2} \mathrm{O}\right)_{6}\right)\right] \mathrm{Cl}_{3} \)
(d) \( \left[\mathrm{Cr}\left(\mathrm{H}_{2} \mathrm{O}\right)_{3} \mathrm{Cl}_{3}\right] \)
