In the molecule \(\text{SF}_4\) the axial S-F bonds are 164 pm long while the equatorial S-F bonds are 154 pm long. Assuming bond length is inversely proportional to the percentage of s‑character in the hybrid orbital used for the bond, estimate the ratio of s‑character in the axial S-F hybrid orbitals to that in the equatorial S-F hybrid orbitals.

Answer Options

A. 0.78 (axial s‑character is about 78 % of equatorial)
B. 0.85 (axial s‑character is about 85 % of equatorial)
C. 1.06 (axial s‑character is about 106 % of equatorial)
Correct Answer D. 0.94 (axial s‑character is about 94 % of equatorial)
Correct Answer
D
Correct Option:
0.94 (axial s‑character is about 94 % of equatorial)
