Homework 2E.11

Postby Jessica Booth 2F » Thu Nov 14, 2019 1:28 pm

Use Lewis Structures and the VSEPR model to give the VSEPR formula for each of the following species and predict its shape:
a)sulfur tetrachloride
b)iodine trichloride
c) IF4-
d)xenon trioxide
What is the VSEPR formula for each part and how do you find it?

The VSEPR formula is AXnEn.
A: central atom
Xn: number of bonding electrons (electrons connected to central atom)
En: number of lone pairs

Draw the lewis structure and you'll find everything you need for the formula!

The VSEPR formula follows: AXnE where A is the central atom, X is the number of bonded atoms to the central atom and E is the number of lone pairs. From this combination of numbers, we can draw the Lewis structure of the molecule and determine its shape.

So for example in iodine trichloride the VSEPR formula would be AX3E2 because there are three bonds to the central atom and two lone pairs on the central atom.
