Reduction of Camphor Lab 1) Provide a mechanism that accounts for the formation of both Borneol and Isoborneol. 2) In lecture we have consistently discussed the fact when we add to a sp^2 hybridized carbon we normally see no facial preference. Use your mechanism to explain why more isoborneol is formed from the reduction reaction. How would you expect the product distribution to change if methyl groups are missing from the camphor structure.

T-pentyl Chloride Lab
1. Define Le Chatilier’s principle, and describe how it applies
to the synthesis of t-pentyl chloride in concentrated HCl,
or the conversion of t-pentyl chloride to
t-pentyl alcohol during the aqueous extraction.
2. When doing boiling point determination with a capillary tube
and boiling bell, what is the gas that is appearing in slow bubbles
when t-pentyl chloride is heated to 70 °C?

What would have been the best starting materials for the
synthesis of R-2-ethoyxbutane?
3. A student wanted to make R-2-ethoxybutane, using the Williamson ether synthesis. He remembered that the Williamson synthesis involves an SN2 displacement, which takes place with inversion of configuration. He ordered a bottle of S-2-butanol for his chiral starting material. He also remembered that SN2 goes best on primary halides, so he made ethyl bromide and S-2-sodiumbutoxide. After warming these reagents together, he obtained an excellent yield...
