A compound with 9 σ bonds and 1 π bond has a molecular formula of C₄H₆. Which carbon has a bond angle closest to 109.5°?

CH₃CH=CHCH₂ fits C₄H₆ with 9 σ (6 C-H, 2 C-C, 1 from C=C) and 1 π (C=C). The first carbon (CH₃) is sp³, with a 109.5° bond angle.

Which molecule has a see-saw shape with an axial-equatorial bond angle of approximately 86°?

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.
