  • Ester - 1162 Words
    chemistry lab report esterification BY MOHAMED ALKHARUSI GRADE 12 BIL Introduction Esters have a very sweet fruity smell. Naturally occurring esters are found in fruits. An ester is a product of the reaction of an acid (usually organic) and an alcohol (the hydrogen of the acid R-COOH is replaced by an alkyl group R'). Esters mainly result from the condensation (a reaction that produces water) of a carboxylic acid and an alcohol. The process is called esterification. This reaction...

  • Ester - 428 Words
    ------------------------------------------------- Definition Esters are chemical compounds consisting of a carbonyl adjacent to an ether linkage. They are derived by reacting an oxo acid with a hydroxyl compound such as an alcohol or phenol. Esters are usually derived from an inorganic acid or organic acid in which at least one -OH (hydroxyl) group is replaced by an -O-alkyl (alkoxy) group, and most commonly from carboxylic acids and alcohols. That is, esters are formed by condensing an acid...
