A molecule with a seesaw molecular geometry has a bond angle of
A)

Question

A molecule with a seesaw molecular geometry has a bond angle of
A) <120° for equatorial bonds and <90° for axial bonds.
B) 180°.
C) <90°.
D) 120° for equatorial bonds and 90° for axial bonds.
E) 120°.

Quizplus · Accepted Answer

A molecule with a seesaw molecular geometry has four electron groups around the central atom, including one lone pair. The lone pair occupies an axial position, which causes the bond angles to deviate from the regular tetrahedral angle of 109.5°. The equatorial bonds in a seesaw arrangement have bond angles of approximately 120°, while the axial bonds have bond angles of approximately 90°. Therefore, the best choice is A, which correctly describes the bond angles in a molecule with a seesaw molecular geometry.
