Introduction: A molecule can be represented on paper by either a molecular or

structural formula. A molecular formula indicates the number and kind of each atom. It

does not give the shape or actual arrangement of the atoms. Ex.

Structural formulas are 2 dimensional. They do not show angles true to the shape of the

molecule.



H—O—H

H—N—H

H—C—H

By using special notations, the following symbols can be used to show how the bonds are

in a 3-D figure.

A bond in the plane of the paper

A bond below the plane of the paper (dash)

A bond above the plane of the paper (wedge)

Part 1:

1. Notes from video. Be sure to include:

a. What VSEPR is.

b. What the 5 VSEPR shaper are

c. A chart showing VSEPR name how many atoms are bonded to the central

atom, and how many unshared pairs

d. polar and non-polar

e. intermolecular forces

2. Draw the 5 3-D VSEPR shapes, name each shape and identify the bond angles.
