For each compound below, decide whether cis and trans isomers are possible. If isomerism is possible, draw the other isomer.
Organic chemistry is a bit like cooking. Later in this course we will study “recipes” for preparingnew molecules. A common instruction in such recipes is “add a strong acid” or “add a strongbase” (rarely are they added at the same time since a violent reaction ensues). You will see theseterms frequently from now on, and are expected to be able to recognize them or draw theirstructures from memory. Memorize them before next class.
Now consider the fully formed molecule on the right side of Figure 3.7. a. Draw a Lewis structure of this molecule. b. Identify orbital representations of the two bonds and three bonds in Figure 3.7, andmatch these with representations of bonds on the Lewis structure you just drew.

What did the student omit from his drawing? b. What is the actual HNH bond angle of ammonia (based on the draw g above, right)? c. Explain why water, ammonia, and methane (shown below) all have about the same bondangles (close to 109.5°) even though they have different numbers of bonds.
Using cartoon representations, draw a molecular orbital mixing diagram for a CO bond. In your picture, consider the relative energies of C and O and how this changes the resulting bonding and antibonding molecular orbitals relative to a CC bond.
