What is the molecular geometry clbr3?

Answer 1

It would be "T" shaped.

ClBr3 is Chlorine Tribromide. Chlorine and Bromide each have 7 balanced electrons, so 7+7(3) is 28 balanced electrons. In a Lewis Drot structure, you'd start by having the three bromides surrounding the chlorine atom. Each bromide would have eight dots, sharing two of those dots with chlorine. Chlorine can have an expanded octet, so the chlorine atom would have four total dots at its top. That would make for 28 balanced electrons.

Answer 2

The molecular geometry of ClBr3 is T-shaped. It consists of a central chlorine atom surrounded by three bromine atoms, with two atoms in a plane and one above/below the plane.
