1. A Review of General Chemistry

Draw the molecular orbital picture of the following molecules and ions. In each, how many electrons are in the p orbital on the central atom? (c) AlCl₃

Explain why a σ bond formed by overlap of an s orbital with an sp³ orbital of carbon is stronger than a σ bond formed by overlap of an s orbital with a p orbital of carbon.

What is the hybridization of all the atoms (other than hydrogen) in each of the following?

What are the bond angles around each atom?

i. H₃O⁺

j. H₂C═O

For each of the following compounds and ions,

1. Draw a Lewis structure.

2. Show the kinds of orbitals that overlap to form each bond.

3. Give approximate bond angles around each atom except hydrogen.

b. [CH₂OH]⁺
