Tetrahedral complexes of the types of [M...

Tetrahedral complexes of the types of `[MA_(4)]` and `[MA_(3)B]` (where M = central metal, A,B = achiral ligands) are not able to show optical isomerism because

A

these molecules/ion have nonsuperposable minor images

B

these molecules posses a centre of symmetry

C

these molecules possess a plane of symmetry and hence are achiral.

D

these molecules/ion possess `c_(n)` axis of symetry.

Text Solution

Verified by Experts

The correct Answer is:
C
Symmetry plane divides the molecule in two halves such that one half is the mirror of the other.

Why does a tetrahedral complex of the type [MA_(2)B_(2)] not show geometrical isomerism?

For the square planar complex [M(a) (b) (c ) (d)] (where M = central meatal and a, b, c and d are monodentate ligands), the number of possible geometrical isomers are

Assertion : Tetrahedral complexes having two different types of unidentate ligands coordinated with central metal ion will show geometrical isomerism . Reason : Geometrical isomerism arises in homoleptic complexes due to different possible geometric arrangement of the ligands .

For an octahedral complex MX_4Y_2 (M=a transition metal, X and Y are monodenate achiral ligands), the correct statement, among the following, is

Which of the following types of square planer complexes has maximum number of geometric isomer ? where Mn is central metal, A, B, C and D are different monodentate ligands, and AB is an unsymmetrical bidentate ligand.
