Benzil Reduction Introduction The objective of the experiment was to reduce Benzil‚ using sodium borohyride as the reducing agent. In a benzil reduction‚ there are five possible products than can occur‚ specifically a racemic mixture of benzoin‚ racemic mixture of hydrobenzoin‚ or meso-hydrobenzoin. Therefore‚ three different tests were conducted in determining the identity of the product: melting point‚ thin light chromatography‚ and infrared spectroscopy. (a) Mechanism and reaction equation

Cause and effect of air pollution in China In my hometown‚ there are various forms of pollution‚ including air pollution‚ water pollution‚ noise pollution and so forth. However‚ perhaps the most devastating pollution in my hometown is air pollution. Since this menace is of concern to every human being‚ an examination of its causes and effects will be interesting and illuminating. The causes of air pollution seem to stem from carelessness or blatant unconcern. Every Sinic citizen who drives a car that

DEFINITIONS OF OXIDATION AND REDUCTION (REDOX) This page looks at the various definitions of oxidation and reduction (redox) in terms of the transfer of oxygen‚ hydrogen and electrons. It also explains the terms oxidising agent and reducing agent. Oxidation and reduction in terms of oxygen transfer Definitions • Oxidation is gain of oxygen. • Reduction is loss of oxygen. For example‚ in the extraction of iron from its ore: [pic] Because both reduction and oxidation are going on side-by-side

by Lollolcats Smoking‚ Why we do it and the damage it can cause. One of the most common problems plaguing our society all across the world today is the smoking of tobacco. The worst part is‚ most people are aware of the detrimental health effects involved in its use. But why do people begin smoking if they known of the complications that arise from it? Why do they continue you smoke regularly knowing of its irreversible effect upon our bodies? Why is such a deadly product still on shelves

John Heger CMY 211 Lab Section 13 11-30-2011 Borohydride Reduction of Vanillin to Vanillyl Alcohol Introduction: The purpose of this lab was to reduce vanillin to vanillyl alcohol. This lab report recaps the procedure and results of the lab. The chemical process studied in this lab was reduction‚ the process of reducing the number of bonds to oxygen and increasing the number of bonds to hydrogen. Other chemical processes included in the lab were recrystallization‚ melting point‚ and extraction

Oxidation and Reduction Mnemonic: OILRIG Oxidation Is Loss‚ Reduction Is Gain Oxidation → the loss of electrons from an atom or an ion→ always happens at anode (positive electrode) → think anOde (O2 in the electrolysis of water xp) Redox reactions: Reactions involving the transfer of electrons e.g. burning‚ rusting‚ photosynthesis‚ respiration and the browning of apples. happens in three types of reactions: 1. addition of oxygen 2. removal of hydrogen 3. increase in valency (how easily an atom

sustainable economic development and growth are some of the main causes of poverty in developing countries. When the suitable economic development is lacking‚ the availability of work and the ability of individuals to secure an income to support themselves and their families will definitely turn down thereby causing poverty. In addition‚ lack of sustainable agriculture‚ as well as integration and full participation in the global economy will also cause poverty. Economic development leads to the improvement
