Experiment 11: Synthesis of Dibenzalacetone by the Aldol condensation Introduction: The Aldol condensation reaction‚ under basic conditions‚ involves the nucleophilic addition of an enolate ion to another carbonyl group. The resulting product‚ a beta-hydroxy ketone or aldehyde‚ is called an aldol because it contains both and aldehyde group and the hydroxy group of alcohol. Condensations‚ including aldol condensation‚ combine two or more molecules‚ typically with a loss of a smaller molecule (including

Jasmine Land Mrs. Bond GE 100- Grammar and Usage April 23‚ 2013 Argumentative Synthesis: For Abortions Before 1967‚ abortion was illegal in the UK. However‚ backstreet abortions were done‚ often ending in permanent injury or death. The 1967 Abortion Act was introduced to provide a safe alternative to backstreet abortions (Abortion).

though we are not aware of them and cannot describe them. Freud found the unconscious very important. While our conscious mind may contains only 10 % of our thinking‚ the remaining 90% of our thinking may be categorized as our unconscious mind. 3. Analysis of dreams Freud thought that by analyzing our dreams‚ it’s possible to uncover our thoughts‚ wishes or desires hidden in our unconscious mind. According to Freud‚ we may analyze the “manifest content” as well as the “latent content” of a dream.

PREPARING CYCLOHEXENE FROM CYCLOHEXANOL INTRODUCTION Alkenes can be prepared in the lab by dehydrating the corresponding alcohol. Concentrated sulphuric and phosphoric acids both act as dehydrating agents. Phosphoric acid is preferred because it gives a higher yield of the alkene. Concentrated H2SO4 reacts with alkenes. SAFETY Eye protection must be worn. Concentrated phosphoric acid is corrosive. Mop up spillages immediately with plenty of water. Cyclohexene and cyclohexanol are

Toxicology Lab 1. In this investigation‚ a wide range of concentrations of Sodium Chloride (NaCl) solution were created and the effects that they had on radish seeds were tested. This ultimately created a doseresponse experiment in which it was detectable whether or not radish seeds were a reliable bioassay for the toxicity of NaCl. The goal of this experiment was to determine a correlation between toxicity and seed germination/radicle

Lab: investigating hooked law with springs Purpose: to find spring constants of different springs using the slope of a graph of change in heights vs. the weight force. Also‚ to be able to understand how spring constants change when you add springs in a series or paralle Pre lab predictions: We predicted that the graph of gravitational force (mg) as a function of stretch (delta x) would look like Data: Spring #1: y = 8.2941x + 0.0685 This table represents the different distances that

Investigation and Preparation of Esterification Lab Introduction Esters are classified as organic compounds commonly derived from carboxylic acids. They are compounded from the reaction of a carboxylic acid with an alcohol in the presence of a strong acid to be used as a catalyst. The formula that represents an ester is R-COO-R where both Rs’ are alkyl groups‚ one which is bonded to an oxygen‚ and the other to a carbon which is double bonded to 1 oxygen and single bonded to the other. Esters

Jazz has been called‚ among other things‚ America’s "only original form‚" showing it’s clear cultural roots in America. In addition‚ jazz historians have touted jazz’s pedigree as "American’s Classical Music." An appreciation and analysis of jazz history forces one to question both the "American" and "Classical" descriptors that past historians have used to label jazz music. Using primarily sources such as "From Somewhere in France" by Charles Delaunay and "An Interview with Wynton Marsalis" by Lolis
