VSEPR Modeling Activity
Directions: For each covalent compound below, write the formula, draw the Lewis dot structure and
calculate the ΔEN for one of the bonds in the compound. If the bonds are polar, draw dipole arrows for
each bond. Then, using your model kits, build each molecule to determine its shape and bond angles.
Finally determine whether or not the overall molecule is polar or nonpolar. Record this information on
the lines provided.
