What is Alcohol? Alcohol Alcohol has been around in various cultures for almost 10 000 years. It is widely used in Canada‚ and is closely associated with parties and celebrations. In 2009‚ alcohol was consumed by 77% of Canadians aged 15 and over (Health Canada). It has a huge presence in the College and University environments‚ and most students claim to have drunk alcohol at some point during their time at school. Alcohol is produced by fermenting and sometimes distilling various fruits

stop or even reduce their consumption. However‚ it is usually not ‘them’ but instead their brain that gives in first. What if there was simply a drug that tricked the brain into submission‚ into believing that there was no rewarding effects from alcohol. Relief could be brought to not only the sufferer but to their family‚ friends‚ body‚ and the healthcare system. Well‚ after extensive research‚ Professor Daryl Davies may just have discovered this effortless drug and he has just shared

estimated 5‚000 teens under the age of 21 die each year as a result of underage drinking. Teens who consume alcohol introduce themselves to the risk of severe‚ life changing health risks. Underage drinking is a factor in nearly half of all homicides‚ suicides‚ and motor vehicle crashes for teens (National Institute on Alcohol Abuse and Alcoholism). Almost 80% of high school students that have tried alcohol are not following the National Minimum Legal Drinking Age‚ of 21 years old. Underage drinking should

Teenage drivers are at a greater risk of death in an alcohol-related vehicle accident than any other population because of inexperience‚ invincible thinking‚ and impaired judgment caused by alcohol. 1. Inexperience plays a major role not only in driving but also in the consumption of alcohol among youth drivers. a. According to the studies done by the Insurance

Investigative question: how are esters formed ? Esters are formed by the reaction of an alcohol and a carboxylic acid‚ usually in the presence of sulphuric acid to catalyse the process‚ or by the reaction of an acyl chloride with a carboxylic acid (this requires no catalyst and is irreversible without additional reactants) are the most common ways used. Others include reactions of certain molecules such as structural rearrangement. Apparatus: Plastic dropping pipettes‚ Beaker (100 cm3 or 250

common Sophomore Organic Chemistry laboratory experiment that has great potential for further research is the acid catalyzed dehydration of simple alcohols. The classic dehydration of 2-methylcyclohexanol experiment that was introduced in Journal of Chemical Education in 1967 Taber(1967)JCE:44‚p620. The rather simple procedure of distilling an alcohol with an aqueous acid has spawned several investigations that have resulted in formal journal articles. At the same time‚ the experiment has retained

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
