CHEMISTRY

Dear Class:

Question 1 – 11:

For each Lewis structure answer the following questions in the space provided:

· I have provided the molecular formula for several compounds.

Provide the Lewis structure for the formula. If you have trouble writing a nice and neat Lewis structure in the space provided.

Please place the drawing on a separate page, labeling each structure with the formula.

· Calculate the formal charge for each atom in the molecule and give the total formal charge for the molecule

· State the number of electron domains around the central atom

· Give the type of molecule based on the ABn formula

· Give the electronic geometry

· Indicate the number of lone pairs attached to the central atom.

· Give the molecular Geometry.

· Indicate if the bond or bonds between the outer atom and central atom are polar or nonpolar

· Indicate if the molecule is polar or nonpolar.

· Indicate the type of hybrid bond is used to form the Vesper structure.
