These remains form sediments eg at the bottom of seas‚ and become buried under layers of sedimentary rock. They decay‚ without air (oxygen)‚ under the action of heat and pressure to form crude oil over millions of years. It is a fossil fuel because it is formed from

methods available for preparing alkyl halides is the replacement of the hydroxyl group of an alcohol. This type of reaction is representative of an important class of reactions in organic chemistry called nucleophilic aliphatic substitution reactions. There are numerous ways of doing this transformation‚ and we will discuss these in lecture. In this experiment you will convert an alcohol to an alkyl halide by reaction with a hydrohalic acid. The overall reaction is shown in equation 1; however the mechanism

Organic vs. non organic There is a vast majority of food in our world today‚ when we consume this food we must stop to think about what exactly it is made of. In today’s society we are always looking for the best healthy foods that are available to us. We want good‚ nutritious‚ healthy foods so that we can live a long and healthy life. We live in a world where we have fast‚ cheap and processed foods all around us. Have you ever considered going a different route? Organic is a different way to eat

The Existence of God Kimberly Mongold PHI 208 Ethics and Moral Reasoning Instructor Kenneth Mentor April 07‚ 2013 Since the beginning of time people have often questioned the meaning of life‚ how the universe was created and the purpose for the wildlife and creatures that roam the earth. These things often lead us to question the existence of God. In order to even begin to answer these complex questions we must uncover the source of all of these occurrences. In this paper I will

impurities have on the melting point of an organic compound? Soluble impurities affect the melting point of a solid in the following manner. a. The presence of an impurity in the molten compound reduces its vapor pressure thus lowering the melting point of the compound. b. Broaden the melting point range. 2. For what tow purpose are melting points routinely used a. To determine the identity of an organic solid. b. To determine the purity of an organic solid. 3. What effects on the measured melting

C H A P T E R 5 Basic Concepts from Organic Chemistry 5.1 | INTRODUCTION The fundamental information that environmental engineers and scientists need concerning organic chemistry differs considerably from that which the organic chemist requires. This difference is due to the fact that chemists are concerned principally with the synthesis of compounds‚ whereas environmental engineers and scientists are concerned‚ in the main‚ with how the organic compounds in liquid‚ solid‚ and gaseous wastes
