CONCEPTS IN ORGANIC CHEMISTRY • Inductive Effect : Inductive effect is defined as permanent displacement of shared electron pair in a carbon chain towards more electronegative atom or group. Types of Inductive effect : 1.Negative Inductive Effect : (—I effect‚ Electron withdrawing effect) when an electronegative atom or group (more electro negative than hydrogen)is attached to the terminal of the carbon chain in a compound‚ the electrons are displaced in the direction of the attached

benefits‚ for example the manufacturing of bleach. Bleach can be used to clean household equipments‚ and to whiten/lighten or clean stains on white cloth. Other than that‚ there is also electroplating. Electroplating is where with electrolysis‚ gives a thin layer of metal to an object‚ where both the object and the metal are submerged into a chemical solution or electrolyte (in molten or aqueous state) which is capable to conduct an electric current and it becomes waste afterwards. The process

The Chemistry of Lipids Experiment #8 Objective To observe the solubility of lipids in polar and nonpolar solvents and to compare saturated and unsaturated fats in their chemical reaction with bromine. The percent fat in a food will be determined by extraction of the fat and weighing it. Introduction Lipids‚ by definition‚ are natural substances that do not mix with water but dissolve in organic solvents. There are several classes of lipids‚ including: fatty acids‚ waxes‚ triacylglycerols
