In ` SiF_6^(2-) ` and ` SiCl_6^(2-)` , which one is known and why ?

A

`SiF_(6)^(2-)` because of the small size of `F`.

B

`SiF_(6)^(2-)` because of the large size of `F`.

C

`SiCl_(6)^(2-)` because of the small size of `Cl`.

D

`SiCl_(6)^(2-)` because of the large size of `Cl`.

Text Solution

Verified by Experts

Out of C Cl_(4) and SiCl_(4) , which one react with water.

Assertion: SiF_(6)^(2-) is known but SiCl_(6)^(2-) is not. Reason: Size of fluorine is small and its lone pair of electrons intersects with d-orbitals of Si strongly.

Statement-I: SiF_(6)^(-2) is known but SiCl_(6)^(-2) in not known Statement-II: Interaction of 'F' lone pair electrons with 'Si' is stronger than that of chlorine and due to smaller size of 'F' steric repulsion will bel less.
