Question
Explain the following:
$SF_6$ is inert towards hydrolysis.
✓

Answer

In $SF_6,$ S atom is sterically protected by six F atoms and does not allow water molecules to attack the S atom. Further, F does not have d-orbitals to accept the electrons donated by $H_2O$ molecules. Due to these reasons, $SF_6$ is kinetically an inert substance.
