Asseration: `SeCl_(4)`, does not havea tetrahedral structure.
Reason: `Se` in `SeCl_(4)` has two lone pairs.

Options

A. If both assertion and reason are true and the reason is the correct explanation of the assertion
B. If both assertion and reason are true but reason is not the correct explanation of the assertion.
C. If assertion is true but reason is false
D. If the assertion and reason both are false.

Answer

C

Explanation

`SeCl_4` possess see saw geometry, which can be regarded as a distorted trigonal bipyramidal structure having one lone pair (lp) of electrons in the basal position of the trigonal bipyramidal. See-saw geometry of `SeCl_4` molecules arises due to the `sp^3 d` hybridisation of the central atom. The distortion in shape is due to the presence of one lone pair of electrons
