Making an Ester Esters are made by reacting a carboxylic acid with an alcohol (a base). Esters are organic salts. Ethanoic Acid+Ethanol O-H H Ethyl ethanoate+Water O-C-C-H H H H H H-C-C H H O CH 3 COOC 2 H 5 H 2 O

Depending on the alcohol and acid used, many different fragrances can be made.

WARNING!! The alarm pheromone of bees makes them attack would be invaders. The pheromone is the ester 3-methylbut-1-ylethanoate, which also happens to be the principal component of banana oil. Don't eat bananas near a beehive!
5
Naming Esters Name the alcohol part first Remove the ‘anol’ and add ‘yl’ e.g. if using pentanol it starts with pentyl Name the carboxylate second Remove the ‘anoic acid’ and add ‘anoate’ e.g. if using ethanoic acid, it ends with enthanoate. Pentanol + ethanoic acid pentyl ethanoate + water
