# Geometry and Bond Angles: Iodine Trichloride

CHEM-IOKABB

Below are three sketches of iodine trichloride. All illustrate its trigonal bipyramidal electron pair geometry.

Use these sketches to help determine which of the following statements are true.

Select ALL that apply.

A

Structures A, B and C are resonance structures of each other.

B

The chlorine atoms in B are in the equatorial positions of the trigonal bipyramid.

C

Aside from the 180${ }^{ \circ }$ Cl-I-Cl angle in C, the other Cl-I-Cl angles are approximately 90${ }^{ \circ }$.

D

The most stable form of the molecule is B because the non-bonding pairs of electrons are 180${ }^{ \circ }$ apart.

E

The molecular geometry of C is T-shaped.

F

A and C are the same molecule. To make C, all one needs to do is to rotate A appropriately.
