Q. Consider the following complexes.
(i)

[C r (E D T A)]^{-}

(ii)

[R u (e n)_{3}]^{2 +}

(iii)

[P t (g l y)_{2} C l_{2}]^{- 2}

(iv)

C i s - [C r (C l)_{2} (o x)_{2}]^{3 -}

(v) trans -

[P t (e n) (N H_{3})_{2} (p y)_{2}]^{4 +}

Then find out the value of expression

| p + q |^{2}

p = total number of optically active complexes

q = total number of optically inactive complexes

Q. Assertion :Both cis-1,3-dimethyl cyclobutane and trans-1,3-dimethyl cyclobutane are optically inactive. Reason: cis-1,3-Dimethyl cyclobutane has the plane of symmetry, where as trans form has the centre of symmetry.

Which of the following statements is correct regarding the chirality (optical isomerism) of the cis and trans isomers of the type $M (a a)_{2} b_{2}$ (M stands for a metal, a and b are achiral ligands and aa is a bidentate ligand) ?
