What is the total number of ligands present in $\left[\mathrm{CoCl}_{2}\left(\mathrm{NH}_{3}\right)_{4}\right] \mathrm{Cl}$
$2$
$4$
$1$
$6$
Solution
$\left[\mathrm{CoCl}_{2}\left(\mathrm{NH}_{3}\right)_{4}\right] \mathrm{Cl}$
$\mathrm{Co}$ is linked to $4 \mathrm{~NH}_{3}$ molecules and $2 \mathrm{~Cl}^{-}$ions in coordination sphere.
$\therefore$ Total number of ligands $=6$
