Cyclohexanol Gjulia Vokrri 02-15-2013 Abstract Alkenes can be produced by heating and dehydrating an alcohol in the presence of a strong acid. The purpose of this experiment was to synthesize cyclohexene by dehydration of cyclohexanol and to detect the presence of a double bond in the alkene. The dehydration reaction using distillation was performed using two acid catalysts‚ 85% phosphoric acid and

SYNTHESIS OF TRANS-9-(2-PHENYLETHENYL) ANTHRACENE (A WITTIG REACTION) Introduction: The purpose of this experiment is to convert carbonyl compounds to alkenes using Wittig reaction. In this case we will be synthesizing Trans-9-(2-phenylethenyl) anthracene from benzyltriphenylphosphonium chloride and 9-anthraldehyde. We will also aim to obtaining a high percent yield and purity for the synthesis of Trans-9-(2-phenylethenyl) anthracene. The mechanism for this reaction goes thus:

Economic value addition by Indian Banks: A study Abstract This research paper studies Indian bank’s profile to demonstrate a direct correlation between the investment in stakeholder relationships and corporate performance. Many Indian banking seems to have destroyed shareholder’s wealth over a period of time and only a few have positively contributed to their wealth. With the help of EVA (Economic Value Added) and MVA (Market Value Added) which tell what the institution is doing with investor’s

OBJECTIVE: The purpose of this experiment is to practice the addition of vectors graphically and analytically and to compare the results obtained by these two methods. APPARATUS: Cenco force table with pulleys. Metal ring‚ strings‚ weight hangers and weights. Rulers and protractors. The force table provides a means for applying known forces at one or more points and in various directions in the horizontal place. The forces are the tensions in strings which pass over pulleys attaches to the

Experiment 1: Mechanism of Nitrile Oxide and Alkene Cycloaddition 1. Purpose: to clarify the mechanism for the cycloaddition reaction between benzonitrile oxide and an alkene‚ and to test the regiochemistry of the reaction between benzonitrile oxide and styrene. 2. Plan: Each student in a group of three will work to create a reaction with the Benzonitrile Oxide with‚ cis-stilbene‚ trans-stilbene‚ or styrene in an Erlenmyer flask. With this Reaction solution thin layer chromatography will be

Subject: Experiment 23: Stereochemistry of the Addition of Bromine to trans-Cinnamic Acid Introduction/Abstract: The purpose of this experiment was to carry out the bromination of trans-cinnamic acid‚ to determine the stereochemistry of the dibromide product of 2‚3-dibromo-3-phenylpropanoic acid‚ and find out whether the reaction proceeds by the usual bromonium ion mechanism or some other mechanism. In this experiment trans-cinnamic acid was mixed with glacial acetic acid and stirred in which

How to Catch a Criminal‚ Crime Show Addition These days there are a number of crime shows that air on T.V. Some of the techniques for solving a crime are the same on these shows‚ but each has a feature that the others do not present in that show. These shows are considered fictional‚ but some are based on actual events or crimes that have happened. The writer loves to watch these types of shows and attempts to figure out “who did it.” Some people may feel these shows are too vivid or not
