Synthesis of DEET Abstract: For this experiment m-toluic acid was reacted with thionyl chloride resulting in a nucleophilic acyl substitution which could then be used to create DEET with excess diethyl amine (Figure 1). This was done by adding diethyl amine drop wise using a seperatory funnel which resulted in a gas formation which was controlled with a condenser attached to a gas vacuum. The resulting mixture was then washed to remove excess acids and bases and rotovapped. DEET was synthesized

Experiment 23: Synthesis of an Alkene April 5‚ 2013 Purpose: Results and Discussion The weight of our n-Butyl Bromide sample (actual yield) was 0.09g. The percent yield was found to be 4.38%. Only 0.09g of the theoretical 2.055g yield was obtained. The boiling point was 104° C‚ which is higher than the literature value of 101° C. This is due to the sample being somewhat impure‚ as impurities tend to increase boiling point. When IR spectroscopy was performed‚ there were no OH stretches

Synthesis Essay In our world‚ we constantly encounter problems. There will be more significant and life-changing obstacles‚ and also many smaller‚ less threatening ones. But what matters most is not the size or relevance of those challenges‚ but instead‚ it is more important as to how one deals with the problem. Adversity of all different types and sizes reveals one’s character. One type of adversity‚ physical adversity‚ happens in various ways. In Mitch Albom’s book‚ Tuesdays with Morrie‚ Albom

His book focused on six main points: opportunity‚ timing‚ ten-thousand hours‚ meaningful work and legacy. The two main focuses of his concepts were Opportunity and Legacy. I believe he chose those two because when and where you are affect a situation but how you approach it is the battery charge for the situation. Gladwell describes how when opportunity presents itself you should

Malcolm X’s legacy to the struggle for black equality in the USA went far beyond focusing on solely equality. Malcolm X hardly forgot the fact that he was the ‘servant’ and not the ‘master’ of the black nation’s aspirations and dreams. Malcolm X resisted the objective of integration and encouraged blacks to build their own society. ‘We can never win freedom and justice and equality until we do something for ourselves’.[i] He felt they should shield themselves against violence‚ ‘by any means necessary’

replication in a eukaryotic cell is more difficult. DNA of an eukaryotic cell is in chromatin form to fit into the small nucleus for the replication to occur‚ first the DNA should open. This is because it is harder for eukaryotes to carry out DNA synthesis. Replication of DNA in a prokaryote is different from a eukaryote. In a prokaryote they have a single origin where the replication process starts. Also eukaryotes synthesize the same time they are being transcribed‚ and ribosomes will be active

What‚ in your mind‚ determines a legacy? Is it someone that makes a change in the world by standing up for what they believe in or someone that does beneficial things after becoming well known for a bad reason? Nothing of great importance happens over night‚ just like becoming known as a legacy takes many years of great acts and small doses of recognition. With time being one of the greatest factors of determination‚ did William H. Harrison really leave a legacy if he was only president for thirty
