liquid for extracting organic solutes is diethyl ether. Ether is chemically very stable‚ has a low boiling point and is an excellent solvent for most organic compounds. In this experiment‚ a mixture of benzoic acid and a neutral compound ; triphenylmethanol or 1‚2‚4‚5-tetrachlorobenzene is separated into its components by the process so called extraction. The mixture is dissolved in diethyl ether. 1 M of sodium hydroxide‚ NaOH solution is used to extract the benzoic acid in the form of its water

Conclusion: ¬¬The goal of the first part of this experiment was to achieve a 50-50 conversion of fluorene to Fluorenone. In order to achieve the goal of the experiment fluorene was oxidized to Fluorenone. The hydroxide ions from the sodium hydroxide in the presence of Stark’s catalyst would be able to de-protonate the acidic fluorene protons. This would result in the formation of a carbanion which attacks the oxygen from the air resulting in the formation of a hydroperoxide and eventually a ketone

Exp.11) Identification of unknown ketones. Introduction: Given five samples of a known ketone derivative‚ the purpose of this experiment is to identify which unknown ketone derivative corresponds to the five known samples. In other words‚ using specific methods of compound detection‚ it is possible to match an unknown compound with a known compound because similar compounds will display similar characteristics. In this experiment‚ identification of the unknown ketone is accomplished through thin

Abstract: The objective of the experiment was to prepare Benzilic acid by multistep synthesis starting with benzaldehyde. In this setup however‚ product of the first step‚ Benzoin‚ is provided thereby omitting the first step involving the conversion of benzaldehyde. For this experiment‚ the microscale techniques of reflux‚ crystallization‚ and melting-point determination were used. Utilizing these techniques a product yield of 93% for benzil and 57% for Benzilic acid was obtained‚ as well as
