Question

Why SF4 deviates from octet rule wrt central atom​

Answer 1

Answer:

All the three molecules SF6,PCl5andBrCl5 deviate from the octet rule, as the central atom in them contains more than 8 electrons. ... Thus, in SF6, there are 2 covalent bonds and 4 singlet linkages. Thus, the S atom and six F atoms in SF6 contain 8 electrons each.

Answer 2

Answer:

sulphur has a covenant d orbital which allows it to form extra bonds. this increase its bond order and hence makes it more stable
