Select the correct statement set? ( 1 ) Bis-(glycinato) Zinc (II) is optically active ( 2 ) [ N i C l 4 ] 2 - and [ P t C l 4 ] 2 - differ in shapes ( 3 ) [ N i ( C N ) 4 ] 2 - and [ N i ( C O ) 4 ] have same magnetic moment 4 Cis- Co ( NH 3 ) 2 en 2 cannot show optical activity

TestHub · Accepted Answer

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 $[P t C l_{4}]^{2 -}$ differ in shapes i.e. tetrahedral and square planar respectively
(3) $[N i (C N)_{4}]^{2 -}$ and $[N i (C O)_{4}]$ have zero magnetic moment
(4) As cis- $[C o (N H_{3})_{2} (e n)_{2}]$ can show optical activity.
