Megan Entwistle‚ Maria Amos‚ and Paul Golubic CHEM 0330 Organic Lab 1 Sodium Borohydride Reduction: Diphenylmethanol from Benzophenone 11/16/11 Introduction Redox (shorthand for REDuction-OXidation) reactions are chemical reactions in which the oxidation state (or oxidation number) of atoms has changed. Oxidation can be observed through the loss of electrons or an increase in oxidation state by an atom‚ ion or molecule. Reduction describes the gain of electrons or decrease in oxidation state

of oil: 1. At room temperature oils liquid. 2. Oils contains large proportion of unsaturated fatty acid. 3. Oils are insoluble in water but readily soluble in Hexane‚ ether‚ benzene‚ Carbon tetra chloride‚ etc. 4. Oils are easily hydrogenated like alkenes. 5. Oils react with Iodine‚ chlorine in aqueous alcoholic solution to form iodo-chloro derivatives. Terms related Definitions: Iodine value: Iodine value may be defined as the number of gm of Iodine that will add across the Carboncarbon double bond

Chemical Formulas Review: Nomenclature and Formula Writing Naming Simple Compounds There are four naming systems you should familiarize yourself with to succeed on the SAT II Chemistry exam. The trick is recognizing which naming system to use. Here are the guidelines: * If the compound starts with H‚ it is an acid. Use the naming acids rules. * If the compound starts with C and contains quite a few H’s and perhaps some O’s‚ it is organic. Use the naming organic compounds rules. *

FOUNDATION IN SCIENCE INTRODUCTION TO PRACTICAL ORGANIC CHEMISTRY – MAKING AND PURIFYING ORGANIC COMPOUNDS Stage 1 – Deciding how much reagent to use Most organic reactions do not go to completion; most reach an equilibrium position with significant quantities of reactants still remaining. In addition‚ separating the desired product from the rest of the reaction mixture‚ and then purifying it‚ will result in the loss of more of the product. The amount of product obtained expressed as a percentage

3.1.1 Identify that matter is made of particles that are continuously moving and interacting The particle theory states that all matter is made up of tiny particles and they are constantly moving/continual state of motion. 1.1.2 Identify the difference between elements‚ compounds and mixtures in terms of particle theory Elements are simplest form substance meaning cannot be decomposed further physically or chemically. They are made up of same type of atoms only e.g. helium‚ oxygen. Compounds

TITLE: EFFECT OF DEEP FAT FRYING ON OIL QUALITY AND SENSORY ATTRIBUTES OF POTATO CHIPS/ CHICKEN NUGGETS ABSTRACT: RBD Palm olein oil is a type of vegetable oils with the ratio of saturation to unsaturation 40%: 60%. Soybean oil is another type of vegetable oils with the ratio of saturation to unsaturation 20%: 80%. In addition to the chemical alterations that occur during frying‚ changes in the oil’s physical and thermal properties‚ such as surface tension‚ viscosity‚ density‚ specific
