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

In this essay I intend to discuss the ideas of John B. Watsson in the Classical Conditioning of emotions. Watson’s theory was developed under the bases of work of a Russian behaviourist Ivan Parvlov. “Classical conditioning is a multistep procedure that initially involves presenting an unconditioned stimulus (ucs)‚ which elits conditioned conditioned response (UCR). Watson was also a behavioursit therefore‚ his work was mostley in the interests of the study of emotions. His theories are in relation

Names: Arian Karim TA Name: Sayantan Das Lab Day & Time: Thursday 7:30-11:40 Lab Section #: Abstract The main purpose of this experiment was to synthesize benzilic acid from benzoin. This requires a multistep synthesis with benzyl as an intermediate product. The first step required HNO3 as an oxidizing agent and the second step required KOH and HCl. The percentage yields of benzil and benzilic acid were 59.5% and 21.9% respectively. The calculated melting

Section 1.4—Converting Units Often‚ a measurement is more convenient in one unit but is needed in another unit for calculations. Dimensional Analysis is a method for converting between units. Equivalents Dimensional Analysis uses equivalents. What is an equivalent? Two measurements that have the same meaning. Ex: What happens if you put one over the top of the other? See your reference sheet for some common equivalencies. We can use these conversion
