SF(6) is known but SC(6) is not. Why?...

`SF_(6)` is known but `SC_(6)` is not. Why?

Text Solution

Verified by Experts

Fluorine is a much stronger oxidising agent than chlorine, therefore, it can easily oxidise sulphur to its maximum oxidation state of+6 and hence frms `SF_(6)`. Chlorine, on the other hand, being a weaker oxidising agent can oxidise sulphur at the maximum to its +4 oxidation state and hence can form `SCI_(4)` but not `SCI_(6)`.
