Question
Explain optical isomerism in co$-$ordination compound.
✓
Answer
$\rightarrow$ Optical isomers are mirror images that cannot be superimposed on one another.
$\rightarrow$ These are called as enantiomers.
$\rightarrow$ The molecules or ions that cannot be superimposed are called chiral.
$\rightarrow$ The two forms are called dextro $(d) $ and laevo $(1)$ depending upon the direction they rotate the plane of polarised light in a polarimeter
$\rightarrow$ Dextro $(d)$ rotates plane polarised light to the right, and leaevo $(1)$ rotates plane polarised light to the left.
$\rightarrow$ Optical isomerism is common in octahedral complexes involving didentate ligands
$\rightarrow$ In a coordination entity of the type $\ce{[PtCl_2(en)_2]^{2+}},$ only the $cis$ isomer shows optical activity.
