ChemistrySingle correct+4 / -1Question 63 of 90

In the structure of $\mathrm{SF_4}$ , the lone pair of electrons on S is in.

equatorial position and there are two lone pair - bond pair repulsions at 90°.

equatorial position and there are three lone pair - bond pair repulsions at 90°.

axial position and there are three lone pair - bond pair repulsion at 90°.

axial position and there are two lone pair - bond pair repulsion at 90°.

Answer and worked solution

Official answer: A

$\mathrm{SF_4}$ is a see-saw: the lone pair sits equatorial, where it has only two 90° repulsions (with the axial bonds).

(A)
