The alkylation of 1‚4-dimethoxybenzene is very favorable because of the presence of two methoxy groups. The groups act as activators to electrophilic aromatic substitution because of their ability to donate electrons through resonance. This enhanced activation helps favor the initial substitution. After this‚ the ring has two methoxy groups and an alkyl group attached to it. The addition of the alkyl group further activate the ring for another electrophilic aromatic substitution. The addition of

Using Scientific Notation Geo Labs Gioppo 2012 © Introduction We use scientific notation to make it more convenient to write out very large‚ or very small numbers. It also helps us avoid making mistakes when writing the numbers‚ like having one too many (or too less) zeros. Think of it as a short hand system –that happens to be based on powers of ten. You’ve done this before in school‚ remember 101 = 10‚ 102 = 100 103 = 1000‚ etc.? This is the same idea‚ we just write it a little

Introduction Motor unit recruitment is the sequential activation of motor units to perform a certain task. In this lab we examined motor unit recruitment and muscle fatigue by electromyography (EMG) with dynamometry (DYN). When the motor unit in the muscle is activated signals are then generated‚ which result in muscle contraction. The impulse generated are a bit weak‚ yet can still be detected by the electrodes‚ EMG and is coupled by a measurements of power‚ DYN. When all the motor units reach

AP Lab #5 Plant Pigments/Photosynthesis I. Identifying the Effects of Different Variables of Light and Carbon Dioxide on the Rate of Photosynthesis and Observing the Separation of Pigments Through Chromatography II. Introduction Plants have a variety of pigments‚ all of which absorb a different color of light. The three main pigments are chlorophyll a‚ chlorophyll b and carotenoids. Chlorophyll a is the primary plant pigment that absorbs red and blue light‚ which ultimately appears green to the human eye

This experiment involved a substitution reaction to perform synthesis of 2-phenylethanol to get (2-bromoethyl)benzene. Using NaBr in an acidic solvent of H2SO4 with H2O present‚ this synthesis was possible. Subsequent evaluations using TLC and then analyzed samples by Gas Chromatography were done to evaluate the results. Using SN2 reactions‚ primary alcohol is going to be converted to alkyl halide. Since the reaction can be reversed‚ the strong sulfuric acid was to make sure the product would indeed
