Here statement 1, 2 and 3 are correct while 4 is incorrect.

(1) Bis-(glycinato) Zinc (II) is optically active

(2)

[N i C l_{4}]^{2 -}

and

[PtC l_{4}]^{2 -}

differ in shapes i.e. tetrahedral and square planar respectively

Here statement 1,2 and 3 are correct while 4 is incorrect.

(1) Bis-(glycinato) Zinc (II) is optically active

(2)

[N i C l_{4}]^{2 -}

and

[PtC l_{4}]^{2 -}

differ in shapes i.e. tetrahedral and square

planar respectively

(3)

[N i (CN)_{4}]^{2 -}

and

[N i (CO)_{4}]

have zero magnetic moment

(4) As cis-

[C o (N H_{3})_{2} (e n)_{2}]

can show optical activity.
