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

effective is it as a means of crime prevention? During the previous era‚ the spread of closed circuit televisions (CCTV) in United Kingdom has been increased in an obvious trend. £38 million has been proved by the British Home office in order to build up local surveillance systems before 1994. What is more‚ during 1995 to 1999‚ £170 million has been made accessible to enhance this system (Phillips‚ 1999‚ p. 123). According to John Burn-Murdoch (2012)‚ the crime statistics from the police office

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

More Beer Reduction in Workforce Exercise More Beer‚ Inc. is a 25 million dollar a year micro brewing company heavily involved in the direct marketing of its various micro brew products. In order to cash in on the internet selling boom‚ More Beer‚ Inc. opened two new marketing and direct distributions channels (www.morebeer.com & www.iamthirstyformorebeernow.com). Soon after these websites went live‚ technology problems‚ together with sluggish sales killed the company’s profits.

experiment of making borneol from camphor (FIGURE-3) is performed in two different methods‚ Sodium Borohydride Reduction and Meerwein-Ponndorf-Verley Reduction‚ to compare the relative product ratio of borneol to isoborneol. The concept of reduction and also oxidation‚ the opposite procedure of reduction‚ deals mostly with electron transfer between atoms. It will not be elaborated here‚ but the reduction procedure involved in this experiment is basically adding hydrogens and losing the carbon-oxygen double

central to individual self-actualization‚ but also to social cohesion‚ economic development and democratic consolidation (Wabara in Alemika and Chukwuma 2004). The Nigeria Police is by law charged with the responsibility of preventing and detecting crime‚ preserving peace and order and enforcing all laws and regulations. The duties placed on the Police are indeed overwhelming. The task is even more daunting in a growing democracy like ours‚ presently confronted with challenges of nurture and sustainability

LU 3 Oxidation and Reduction Reactions 3.1 Ideas of Oxidation and Reduction Oxidation of an atom can be occurred in the following conditions: 1. Losing an electron from the orbitals. e.g.: A A+ + e- 2. Adding an electronegative element (e.g.: F‚ Cl‚ Br‚ O) to a molecule. e.g.: A + F AF 3. Losing hydrogen

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
