Solution

a
$(i)$ cis $-\left[ Co \left( NH _3\right)_2( en )_2\right]^{3+}$ contains no element of symmetry and is optically active. It has $d$ and 1 forms.

$(ii)$ trans $-\left[ IrCl _2\left( C _2 O _4\right)_2\right]^{3-}$ contains a plane of symmetry and is optically inactive.

$(iii)$ $[ Rh ( en ) 3]^{3+}$ contains no element of symmetry and is optically active. It has $d$ and $l$ forms.

$(iv)$ cis $-\left[ Ir \left( H _2 O \right)_3 Cl _3\right]$ contains symmetry elements and is optically active.
