The molecular geometry of $PF_3$ is $...$.

Although the geometries of $NH_{3}$ and $H_{2}O$ molecules are based on a distorted tetrahedral arrangement,the bond angle in water is less than that of ammonia. Discuss.

The molecule exhibiting the maximum number of non-bonding electron pairs $(l.p.)$ around the central atom is

Among the following species, the $H - X - H$ bond angle $(X = B, N, \text{ or } P)$ follows the order:

Which of the following is the incorrect order of bond angle?
