321944 Assertion :
Complexes of \(\mathrm{MX}_{6}\) and \(\mathrm{MX}_{5} \mathrm{~L}\) type (X and \(\mathrm{L}\) are unidentate) do not show geometrical isomerism.
Reason :
Geometrical isomerism is not shown by complexes of coordination number 6 .

321945 Assertion :
The geometrical isomers of the complex \(\left[\mathrm{M}\left(\mathrm{NH}_{3}\right)_{4} \mathrm{Cl}_{2}\right]\) are optically inactive.
Reason :
Both geometrical isomers of the complex \(\left[\mathrm{M}\left(\mathrm{NH}_{3}\right)_{4} \mathrm{Cl}_{2}\right]\) possess axis of symmetry.
