Functional Groups of Organic Compounds A functional group is a specific arrangement of atoms in the HC derivative other than carbon and hydrogen. Literally‚ the functional group determines the functions of the particular HC derivative in chemical reactions. This means that the specific properties of the HC derivative are due to its functional group. Each functional group is attached to an alkyl radical (R). An alkyl radical is one H atom less than the given alkane. The alkyl radical (R) uses

When reading Superstitions About Rats by Lesley Emmanuel‚ the reader will notice a distinct focus on the portrayal of the female characters in the short story. The women in Lesley Emanuel’s Superstitions About Rats are portrayed in such a way that one cannot label or identify them without referring to their relationships with other characters or the settings that serve to characterise them. It is also quite obvious that each of these characters has an influence on the main character‚ Anniline‚ in

Chem 3418 Organic Chemistry Laboratory I Acid Base Review Definition In general‚ an acid is a substance that can donate a proton (H+) and a base is a substance that can accept a proton. Any proton in an organic molecule can potentially be donated. The most acidic proton in a molecule would be donated first. Any lone pair in an organic molecule can act as the proton acceptor. An acid (HA) reacts with a base (in this case H2O) to form the conjugate base of the acid (A-) and the conjugate acid of the

“Science does not know it’s debt to imagination.” “Men love to wonder‚ and that is the seed of science.” Ralph Waldo Emerson was right on point when he said these two statements. There have been numerous great scientists that have come in and out of this world‚ and there are many to still come. When Emerson said these two quotes‚ he was talking about all of these scientists. The world we live in today would not be the same without the imagination and wonder of scientists; therefore we owe everything

3-2-3-1-Conventional Culture Method (Marks 1972): The infected lesions of the tuberculin positive reactors were collected and placed in to a sterile mortar containing sterile sand. The fat was removed and the suspected parts were cut into minute pieces. Then 2 ml of distilled water added to the mixture‚ homogenized and crushed well until the suspension was obtained. Then 2 ml of H2So4 acid 4% added to the mixture then incubated the mixture at 37 0C for 1/2 h. The mixture was diluted with

suspension of the powdered ore is made with water. To it‚ collectors and froth stabilizers are added. Collectors (e. g.‚ pine oils‚ fatty acids‚ xanthates‚ etc.) enhance non-wettability of the mineral particles and froth stabilizers (e. g.‚ cresols‚ aniline) stabilize the froth. The mineral particles become wet by oils while the gangue particles by water. A rotating paddle agitates the mixture and draws air in it. As a result‚ froth is formed which carries the mineral particles. The froth is light and
