David asks…
Draw Lewis structures and label each with the appropriate geometry?
Draw Lewis structures for the following molecules and label each with the appropriate geometry. CO, NH3, HNO3, H2O2, O3, C2H2, and C2H4 2.

You might do better posting this under chemestry, but wiki has Lewis structures for most compounds.

Joseph asks…
What is the electron pair gemoetry and molecular geometry of H2O2?
When I draw out the lewis structure I get H-O-O-H with two lone pairs on each O. so…which is the central atom? H can never be a central atom so that leaves you with O..but you have two O’s..and if you add it all up you now have 7 “bonds” on your O.(3 from bonding with each other and the H’s and 4 lone pairs)
admin answers:
The structure of hydrogen peroxide is H-O-O-H. The two oxygen atoms are joined by a single bond, and the two lone pairs and the hydrogen-oxygen bond completes all bonds. If you see the lone pairs as bonds, the structure around each oxygen atom is tetrahedral, with both H-O-O bonds in a V-shape, like water.
