Question

Discuss the formation and structure of XF₃ (X = Cl, Br, I) molecule.

Answer 1

Type XY₃ interhalogen compounds have a T-shaped structure and are created when the central atom X undergoes sp³d hybridisation in its first excited state. For example, the figure shows how an XF₃ molecule is formed by sp³d hybridisation as well as its structure.
