Number of stereoisomers possible for the complexes, $\left[\mathrm{CrCl}_3(\mathrm{py})_3\right]$ and $\left[\mathrm{CrCl}_2(\mathrm{ox})_2\right]^{3-}$ are respectively
( $\mathrm{py}=$ pyridine, $\mathrm{ox}=$ oxalate)
  1. $3 \& 3$
  2. $2 \& 2$
  3. $2 \& 3$
  4. $1 \& 2$

Solution


So total stereo isomer $=2$
Geometrical isomer $=2(1$ cis +1 trans $)$
Optical isomer $=3$ ( 2 optically active +1 optically inactive)
Stereoisomer $=3$
