1. What is the molecular geometry of a molecule with four

bonded atoms and one lone pair around the central atom?

A) Tetrahedral

B) Trigonal pyramidal

C) Trigonal planar

D) Bent

Answer: B) Trigonal pyramidal

Rationale: The lone pair occupies more space than a

bonded pair, so it pushes the bonded atoms closer together,

resulting in a trigonal pyramidal shape.

2. What is the bond angle of a molecule with a linear

molecular geometry?

A) 90°

B) 109.5°

C) 120°

D) 180°

Answer: D) 180°

Rationale: A linear molecule has two bonded atoms and no

lone pairs around the central atom, so the bonded atoms are

as far apart as possible, resulting in a 180° bond angle.

3. What is the hybridization of the central atom in a

molecule with a trigonal bipyramidal molecular geometry?

A) sp

B) sp2

C) sp3

D) sp3d

Answer: D) sp3d
