Tetrahedral complexes do not show geometrical isomerism because
the relative positions of the unidentate ligands attached to the central
metal atom are the same with respect to each other Solution

Optical isomers are mirror images that
cannot be superimposed on one
another These 
are 
called 
as
enantiomers The molecules or ions
that cannot be superimposed are
called chiral
