Explain why :
`SF_(6)` is inert and stable but `SF_(4)` is reactive.

SF_(6) is exceptionally stable due to

Explain why: SF_6 forms but not SCl_6 .

The hybridisation and shape of SF_(6) is respectively

Explain why SF_(4) is easily hydrolysed, whereas SF_(6) is resistant to hydrolysis ?

Why is SF_(6) kinetically inert ?

Give reasons for the following observations : Why SF_(4) undergoes hydrolysis but not SF_(6) ? Or SF_(6) is inert towards hydroysis. SF_(6) is much less reactive than SF_(4) . Or (i) SF_(4) is easily hydrolysed whereas SF_(6) is not easily hydrolysed. (ii) Sulpher exhibits greater tendency for calenation than selenium. (iii) Sulpher has a higher tendency for catenation than oxygen.
