Question

The bond angle in ammonia is ${109}^o{28}^{\prime }.$

• A. True
• B. False

Answer 1

The correct option is B False

The figure of $N{H}_3$ is

The bond angle is angle between two $\sigma -\sigma$ bond.

Due to repulsion caused by pair of electrons bond angle is decreased from ${109}^o{28}^{\prime }$ to ${107}^o$
