Question
Which molecule has a see-saw shape with an axial-equatorial bond angle of approximately 86°?
Explanation
In SF₄ , sulfur is sp³d hybridized with 5 electron pairs (4 bonding, 1 lone), forming a see-saw shape. The axial-equatorial F-S-F bond angle is ~86°, and the equatorial bond angle is ~101°, both reduced due to lone pair repulsion.
