CHM 101 Hybridization and Chemical Bonding Objective Question
Take CBT

Question

What is the bond angle in water and why is it less than the tetrahedral angle?
Options
A 180° because of linear geometry
B 120° because of trigonal planar geometry
C 104.5° because of lone pair-bond pair and lone pair-lone pair repulsion
Correct Answer
D 90° because of p orbital overlap
Correct Answer

Option C is the correct answer.

Detailed Explanation

The bond angle in water is a little smaller (104.5°) than the tetrahedral angle, because of the lone pair-bond pair and lone pair-lone pair repulsion which reduces the bond angle.

Hint

The notes provide both the angle and the reason.
