oxidation of the plant extract‚ the steps were done away from direct light. The skin was shaken with ethyl acetate and was kept for 72 hours and was filtered. The filtrate was dried using a rotary evaporator to get one-tenth of its original amount. The functional and phenolic groups present in the resveratrol were tested using standard methods. Aromaticity and the melting point were also determined. In the preparation of the resveratrol derivatives‚ the first two resveratrol extracts were dissolved in dry

Definition of ’Moore’s Law’ An observation made by Intel co-founder Gordon Moore in 1965. He noticed that the number of transistors per square inch on integrated circuits had doubled every year since their invention. Moore’s law predicts that this trend[->0] will continue into the foreseeable future. Although the pace has slowed‚ the number of transistors per square inch has since doubled approximately every 18 months. This is used as the current definition of Moore’s law. History The term

principal element. • Carbon is special because it has 4 bonds. Functional Groups • Organic substances are organized into organic families. • Organic Families – group of organic compounds with common structural features. o Each family has a recognizable physical property and a specific structural arrangement. o Each combination is referred to as a functional group. o Even though many functional groups exist‚ they essentially consist of only 3 main components.

Introduction Esters derive from the reaction between a carboxylic acid and an alcohol (Figure 1). Figure 1. The General Reaction Equation of Ester Formation From A Carboxylic Acid & An Alcohol. Carboxylic acids contain the functional group –COOH whereas in ester’s the hydrogen is replaced with an R denoting any alkyl or aryl group; -RCOOR’. Esters with low-molecular weights are commonly used as components in the flavor’s and odors of many fruits & fragrances’ as well as to enhance foods & beverages

Our Infrared Spectroscopy (IR) spectrum for our Acetaminophen KBr pellet provided a handful of strong peaks and hints that helped us to hypothesize what functional groups might be in Acetaminophen. The peaks that were at the highest wavenumbers were analyzed first. The strong peak at 3325.82 cm-1 was an indicator that there was stretching occurring between a Hydrogen and Nitrogen atom. This signified that Acetaminophen could contain an amide group. The next defined peak is located at 3162.26 cm-1
