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

So total stereo isomer $=2$

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