1 Optical isomers

2 Coordinate isomers

3 Ionization isomers

4 Linkage isomers

COORDINATION COMPOUNDS

28706 Which of the following complex will show geometrical as well as optical isomerism ( $e n =$ ethylene diamine)

1

{[P t {(e n)}_{3}]}^{4 +}

2

P t {(N H_{3})}_{2} C l_{2}

3

[P t (N H_{3}) C l_{4}]

4

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

Explanation:

(d) $[P t (e n)_{2}] C l_{2}$ 341-s37

COORDINATION COMPOUNDS

28707 Which of the following complexes is diamagnetic
