The bond angles of PF3, PCl3, PBr3 and PI3 are 97o, 100o, 101.5o and 102o respectively. This data shows a gradual increase in the bond angle. Explain.

Expert Answer:

As the electronegativity of surrounding atom decreases, the electron pair lie closer to the central atom so the repulsion between the electrons increases and the bond angle also increases.
