Chemistry

1. Draw the structure of bicyclo [3.2.0] heptane.

2. Consider the following compounds:
CH3-CH2-CH2-CH2-CH3
CH3-CH2-CH2-NH-CH3
CH3-CH2CH2-CH2OH

Predict their relative boiling points (rank from low (1) to (3)). Explain answer in terms of the intermolecular forces involved.

3. Draw a three-dimensional sctructure of CH3CL. Include all non-donding pairs in your drawing. Shoe the direction of te molecular dipole and indicate bond angles.

4. Draw orbital pictures of the pi and sigma bond found in the follwoing molecules. Indicate the bond angles in your drawings as well.

a. CH2 - C (triple bond) CH
b. (CH3)2 C=NH

5. Draw the most stable conformation of cis-1, 3-dimethylycylohexane. Explain your answer in terms of axial vs. equatorial positions.

6. Draw the Newman projections f the three confromers of 1, 2-dibromoethane. Label them and indicate which one is most stable.

7. Draw all the possible isomers, including geometric (cis,trans) of the cyclci forms of C4H7CL. Cricle te structure that shows the least amont of ring strain. Name one of your isomers.

8. Draw the lewis structure f carbon disulfide (CS2). Use lines of bonds and dots for non-bonding electron pairs. Account for all the valence electrons.

9. Redraw the structure showing hyridization of carbon and oxygen atoms. Include pi and sigma bonding overlap and the relative geometry of the bonds.

10. Comments on the dipoles (if any) of the bonds and on the over-all dipole moment of the molecule.
