Skeletal Form and Bonds in Caffeine
the skeletal form of Caffeine and the bonds formed in the structure. Please include complete detail for each part. I have part of the problem completed and am looking for confirmation.
a. Draw the structure of Caffeine. Skeletal form only.
b. Locate 2 bonds in the molecule that are obviously polar covalent.
c. What is the hybridization of each O in the molecule?
d. Label each carbon that is not sp^3 -hybridized with its correct hybridization.
e. Are there any sp-C carbons in the molecule? If so, label them.
