VSEPR Molecular Geometry

We Will:
1) Define VSPER Theory
2) Identify easy mistakes

I will Practice using and applying what I have learned

VSEPR

Valence Shell Electron Pair Repulsion

• VSEPR predicts the shapes of molecules based on the idea of electron pairs repelling one another.

• Electrons around the central atom repel and spread out.

Multiple Choice

VSPER (valence Shell electron repulsion) Theory is used to help chemists Identify what?

• electron shells

• shape of molecules

• number of covalent bonds

Multiple Choice

Electrons repel one another because they are ...

• like charges

• opposite charges

• they have an attitude problem

​

VSEPR Theory Chart

A bonding site is any location where a bond occurs or branches from the central atom. We DON'T count a double bond as two bonding sites, but it is still just one.

​

Lone pairs are counted in pairs. They are also only included in the reading of the VSEPR chart if they are found attached to the central atom of the molecule. ​

Multiple Choice

Double and triple covalent bonds are counted as

• 1 VSPER

• individual VSPER bonds

Multiple Choice

In VSPER we count the individual number of electrons?

• NO

• YES
