Simple Neutralisation Reaction Acid + Base Sodium hydroxide Hydrochloric Acid + Na OH H Cl Sodium Chloride + Water (inorganic salt)
H H H O H-C-C O-C-C-H H H H Making an Ester Esters are made by reacting a carboxylic acid with an alcohol (a base). Esters are organic salts. Ethanoic Acid + Ethanol H O-H Ethyl ethanoate + Water CH3COOC2H5 H2O
Most esters have a pleasant odour. 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!
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
What are esters? Ethanol + methanoic acid What would these make?
What are esters? Butanoic acid + ethanol What would these make?
What are esters? What would I use to make this?
