them now. Alcohols are usually named by the first procedure and are designated by an ol suffix‚ as in ethanol‚ CH3CH2OH (note that a locator number is not needed on a two-carbon chain). On longer chains the location of the hydroxyl group determines chain numbering. For example: (CH3)2C=CHCH(OH)CH3 is 4-methyl-3-penten-2-ol. Other examples of IUPAC nomenclature are shown below‚ together with the common names often used for some of the simpler compounds. For the mono-functional alcohols‚ this common

in Philippine Constitution for Academic Purposes (SS10) Presented by: Quiniquini‚ Sharmaine R. September 12‚ 2011 ABSTRACT Alcohol can be good for the body if it is taken in a right way. It can calm us when we are nervous or put us to sleep if we want. However‚ too much intake could of course be dangerous to our health. Pressure to try drugs and alcohol is strong among teens. Many face temptation from peers and close friends‚ who tell them that drugs and drinking are fun and cool. Many

alcoholism is a disease that affects not only the addicted person but it also affects their families as well. Many children who grow up in homes where one or both parents are alcoholics or abuse alcohol will in time need to have help in sorting out all of the issues associated with a parent or parents that abuse alcohol. Sometimes children of alcoholics are physically‚ sexually and emotionally abused. Even when there is no outward abuse the child growing up in an alcoholic family suffers damage. Once a parent

EXPERIMENT 8 BOILING POINT n-Butyl Alcohol n-Butyl Alcohol‚ a four carbon straight chain alcohol‚ is a volatile‚ clear liquid with a strong alcoholic odor; miscible with water. It is flammable strongly with a luminous flame. Formula: C4H9OH Boiling point: 118 ºC Melting point: -89 ºC Tert-Butyl Alcohol Tert-Butyl Alcohol or “2-methyl-2-propanol” is the simplest tertiary alcohol. It is one of the four isomers of butanol. Tert-Butanol is a clear liquid (or a colorless solid‚ depending on

Fischer Esterification is when an carboxylic acid and an alcohol reacts to produce an ester‚ catalyzed by a strong acid to protonate the -OH of the carboxylic acid‚ so it leave as water (Ketcha‚ 58). For Fischer Esterification to occur‚ the reaction must be heated up‚ without boiling away‚ for a prolong amount of time by refluxing the mixture (Ketcha‚ 57). Refluxing is the process in which the boiled solution’s vapors are condense back to a liquid and return to the boiled solution (Ketcha‚ 60). The

considered to be acceptable for a synthesis reaction‚ instead it is considering as a poor yield of ester. The synthesised ester can only have a maximum yield of 70% because for ester in which the carboxylic acid and alcohol are sterically unhindered‚ a same ratio mixture of carboxylic acid and alcohol can only synthesis ester with a maximum yield of 70% ester as the reaction with the same ration of mixture will reach a state of equilibrium‚ which the concentration of all the species will remain constant‚
