What value listed below best approximates the H - O - H bond angle in water?

Question

Quizplus · Accepted Answer

The H-O-H bond angle in water is approximately 104.5°. This value is specific to the tetrahedral geometry of the molecule and the lone electron pairs on the oxygen atom. The other choices are not close to the actual bond angle of water. A bond angle of 90° would indicate a linear molecule, which water is not. A bond angle of 109° is close to the tetrahedral bond angle, but not specific to water. A bond angle of 120° would indicate a trigonal planar geometry, which is not present in water. A bond angle of 180° would indicate a linear molecule, which water is not.
