four days‚ before moving half of the rats to a new location and injecting them with a larger amount of ethanol. The rats that stayed in the same location remained relatively healthy‚ while nearly two-thirds of the rats in the new location died of alcohol poisoning. A similar experiment involving rats and morphine showed that the body can overcompensate for the expected effects of a drug when presented with a smaller dose. Rats were given relatively large doses of morphine for several days‚ and when

How Carboxylic Acids and Alcohols React to Produce Esters: Esters and Ester Production: Esters are abundant and ever present‚ and are the chemical basis of almost all fatty acids and oils. Small esters are responsible for the aroma of fruits‚ perfumes and‚ by extension‚ wines and other alcohols. Esters are formed when a carboxylic acid and an alcohol chemically combine‚ losing a molecule of water in the process. Carboxylic acids are organic molecular compounds that form a homologous series

reacts with an alcohol‚ the products are water and ester. The overall reaction is reversible and slow‚ as soon as the products begin to form‚ hydrolysis a reverse reaction of esterification occurs. To ensure the reaction is complete an acid catalyst is commonly used. The catalyst is usually concentrated sulphuric acid. This experiment covered 4 techniques; they are distillation‚ refluxing‚ extraction‚ and esterification. Firstly‚ esterification and refluxing‚ the acid and alcohol are first warmed

Preparation u Alcohols when heated in presence of H2SO4‚ H3PO4‚ P2O5‚ Al2O3 or BF3 undergo loss of water molecule with the formation of alkene. Conc. H2SO4 180oC H3PO4/P2O5 200oC Al2O3/BF3 350oC CH3-CH=CH2 + H2O CH3-CH2-CH2-OH CH3-CH=CH2 + H2O CH3-CH=CH2 + H2O u u Mechanism: In the first step OH group of the alcohol is protonated in a fast reversible reaction. Unlike OH group‚ protonated OH group is a good leaving group. Step 1: CH3 CH3-C-CH3 + H+ HO CH3 CH3-C-CH3 H2O+
