Which of the following molecules is expected to have an octahedral shape?

Question

1. PCl₃
2. PCl₅
3. SF₄
4. SF₆

Answer 1

SF₆ would have an octahedral shape.

It would have S as the central atom with 6 F atoms bonded to it. There would be no lone pairs of electrons on the central S atom. This gives rise to an octahedral shape.
