Draw Lewis Structure and structural formulas for molecules and label.?

Question

I need help. For the following I need to know as follows:

Lewis Structure and structural formulas

PH3

CO2

SO2

Label each BOND as Polar or non polar - make sure to describe the BOND not the molecule

Give the shape of each MOLECULE & describe whether each MOLECULE is polar or non polar? Soluble or insoluble in water?

Answer 1

All the BONDS are polar as there are no bonds that have plane (perpendicular) symmetry through the bond. Non-polar molecules need 3-fold planar symmetry - only CO2 has it here.

With info you should be able to draw octets and see the shapes.

Remember the both S and O have 6 e's in valence shell; thus, 18. Count the e's in the previous answer.
