Experiment 14 SN2: Synthesis of 1-Bromobutane Alkyl halides can be prepared from their corresponding alcohols via an acid catalyzed substitution reaction. The mechanism of these acid catalyzed substitution reactions are labeled as SNI (substitution, nucleophilie, unimolecular) and S2 (substitution, nucleophilie, bimolecular). Tertiary alcohols follow the Syl route, primary alcohols follow the S2, route and secondary alcohols can follow either path. Sth CyHe 81 CH?

A2. A scientist has a beaker of water. She adds 10 ml of sunflower oil into the beaker of water and stirs it. The water becomes cloudy, then gradually clears as an oily layer forms on the surface. The structure of sunflower oil is shown below: o O What is happening here? Why does the oil behave this way in the solvent water? Draw diagrams of chemical structures and use thermodynamic terms and equations to...

Reduction of Ketone
During this experiment we had to reduce 9-fluorenone to
9-fluorenol. We took pure fluorenone and fluorenol and mixed with
acetone then spotted them on lanes one and two on our TLC plate. We
then took 9-fluorenone and and mixed with methanol, and began
mixing. We then spotted the methanol fluorenone mixture on our TLC
plates in different time intervals, lane three 0 seconds, lane four
