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

the resolution “We should question authority” the following parts are vague: “we”‚ “question” and “authority”. By we I mean all people‚ by question I mean to think rationally about it and by authority I mean anybody who has to power to give us orders. Unfortunately in everyday live a lot of people follow orders blindly leading to dangerous situations. 3. Therefore I made the following case: “We should think rationally before following orders from the authority”. Points: 1st point 1. My first

Authority in the public services Authority means the right or power to enforce rules or give orders. To do this they need legislations to enforce their laws‚ to function properly the uniformed pubic services need to have legislations. The extent of authority relates to the limit of control held by an individual or organisation. The limit of control is governed by the job description of the role‚ as well as the jurisdiction‚ with authority coming either from statute or company policy. An example

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

DIRECTING Definition- it’s the interpersonal aspect of managing by which subordinates are led to understand and contribute effectively and efficiently to the attainment of enterprise objectives. A good leader evokes zeal and confidence in subordinates. Without this quality the enterprise may be superbly organized and staffed and many have excellent plans but its performance may be mediocre.

Argument from authority The basic structure of such arguments is as follows: Professor X believes A‚ Professor X speaks from authority‚ therefore A is true. Often this argument is implied by emphasizing the many years of experience‚ or the formal degrees held by the individual making a specific claim. The converse of this argument is sometimes used‚ that someone does not possess authority‚ and therefore their claims must be false. (This may also be considered an ad-hominen logical fallacy – see

Synthesis of Cyclohexanol Author: Ahmed Ayyash 06/06/13 Introduction: In this experiment‚ cyclohexanol was prepared from an initial cyclohexene. However‚ this occurred over a number of steps‚ these are out lined below. 1.
