SF6 is known but SCl6 is not. Why?...

`SF_6` is known but `SCl_6` is not. Why?

Text Solution

Verified by Experts

Fluorine atom is smaller in size, so six `F^(-)` ions can surround a sulphur atom. The case is not so with chlorine atom due to its large size. So, `SF_6` is known but `SCI_6` is not known duc to interionic repulsion between larger `Cl^(-)` ions.
