# 11. The compound(s) that exhibit(s) geometrical isomerism is/are (2009)

(a) ( left[mathrm{Pt}(mathrm{en}) mathrm{Cl}_{2}right] )

(b) ( left[mathrm{Pt}(mathrm{en})_{2}right] mathrm{Cl}_{2} )

(c) ( left[P t(e n)_{2} C l_{2}right] C l_{2} )

(d) ( left[mathrm{Pt}left(mathrm{NH}_{3}right)_{2}right] mathrm{Cl}_{2} )

Solution

Both ( left[mathrm{Pt}(mathrm{en})_{2} mathrm{Cl}_{2}right] mathrm{Cl}_{2} ) and ( left[mathrm{Pt}left(mathrm{NH}_{3}right)_{2} mathrm{Cl}_{2}right] ) are capable of showing

geometrical isomerism.
