A mixture of methanol-water was distilled (Simple distillation, fractional distillation) and temperature at which the sample boiled was recorded. The results of both distillations were compared and graphed (mL of distillate vs Temperature). Done in lab, before COVID 19. For Hunter College's CHEM 22...

A secondary alcohol (cyclohexanol) was oxidized into a ketone (cyclohexanone) using an oxidizing agent (Hypochlorous acid). By manipulating solubility differences between these two cyclic structures, the two were separated to obtain a single and/or both products, which will be identified using Infra...
