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

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

This is because alcohol is more flammable‚ and burning alcohol causes it to vaporize‚ along with the water present in the solution.

MERITS In a study conducted by Shivakumarswamy et al.‚ 2012‚ the diagnostic utility of cell block preparation using 10% alcohol-formalin as a fixative was compared with the conventional smear. In this study it was concluded that the 10% alcoholic fixative is optimal for the cell block technique‚ in that‚ they got better cellularity as formalin minimized the cell loss by forming

Reactions of Carbonyls-Aldehyde/Ketone Analysis: Introduction: The carbonyl group is a rich source of many important reactions in organic chemistry‚ with two fundamental properties that are primarily responsible for its diverse chemistry. The first is the polarization of the. Carbon-oxygen pi bond‚ owing to the relatively high electro negativity. The second property of a carbonyl function is to increase the acidity of the alpha-hydrogen atoms‚ which are the hydrogen’s

preventing drinking in general‚ especially with minors and making the punishments for it so severe that it has‚ what I believe‚ more of a negative effect‚ especially with under aged drinking. As law enforcement and penalties have become tougher on alcohol-related offenses‚ harsher penalties are being handed down to drinkers than abusers of illegal drugs‚ (simple possession of which is strictly not allowed in the first place!) For instance‚ MIP’s punish under-age drinkers with months of probation as
