Question

What is the shape and bond angle of an ammonia molecule (NH₃)?
Options
A Tetrahedral, 109.5°
B Trigonal planar, 120°
C Pyramidal, 107°
Correct Answer
D Linear, 180°
Correct Answer

Option C is the correct answer.

Detailed Explanation

Ammonia (NH₃) has three bonding pairs and one lone pair on the central nitrogen atom. The lone pair repulsion compresses the bond angle from the ideal tetrahedral angle of 109.5° to approximately 107°, resulting in a trigonal pyramidal shape.

Hint

The lone pair in ammonia distorts the tetrahedral geometry.
