PLEASE EXPLAIN THE NEWMAN PROJECTION !!! HOW
Compounds 1 and 2 exhibit an oxetane ring (a four-membered ring containing an oxygen atom), which is a very important structural feature in a number of natural products. For example, an oxetane ring is present in the structure of taxol, used in the treatment of breast cancer. When either 1 or 2 is treated with TsCI and pyridine, followed by t-BuOK, the Zaitsev elimination product dominates, despite the use of a satirically hindered...

Please answer all 4 questions
1) Draw condensed structure formulas for the following
compounds
2) How would you describe the difference between saturated and
unsaturated hydrocarbons and what is a distinguishing feature of
aromatic hydrocarbons?
5) Do you expect the aromatic hydrocarbons to react in a similar
way to the cyclic alkenes, since they are both cyclic compounds and
have a double bond? explain
6) write the structure of the product. if no reaction occurs
write NR
