Chem 223 Samenvattingen, Notities en Examens

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 Infrared (IR) spectroscopy (all IR included in lab report). Lab done online, during COVID-19.

A Thin Layer Chromatography (TLC) Plate was used to calculate the ratio to the front (R​f)​ values for the the given compounds: anthracene, cholesterol, 1,4-naphthoquinone, ​p​-nitroaniline. CHEM 223. Hunter College, CUNY. Experiment done in lab, before COVID-19. Includes images, figures, and tables.

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 223. Includes all work for post lab questions.

Deprotection of the naphthalene 119 with trifluoroacetic anhydride and in situtrapping of the sensitive aminonaphthalene 120 by addition of the diketone 117,eventually provided the target molecule ancisheynine (78) as its TFA salt in 48%yield
