Question

According to valence bond theory, the predicted bond angle for $H_{2}O$ is:

• A. ${90}^0$
• B. ${109}^{o}28$
• C. ${107}^{o}18$
• D. ${104}^{o}28$

Answer 1

The correct option is B ${109}^{o}28$

According to valence bond theory, bond angle for $H_{2}O$ is ${109}^{o}28$. It doesn't consider the lone pair repulsions on the bonding electrons.
