The following diagram shows the reactions of alcohol and carboxylic acids to make esters. Scroll down the page for examples and explanations.
Making esters from alcohols and acids
How to prepare an Ester from an alcohol and acid and separate by distillation?
In this activity, we will prepare a pure sample of ethyl ethanoate from ethanoic acid and ethanol.
Drawing and naming esters
How to name and draw the structures for esters (which form from alkanols and alkanoic acids in the process of esterification)?
alkanoic acid + alkanol ⇆ ester (akyl alkanoate) + water
ethanoic (acetic) acid + methanol → methyl ethanoate (acetate)
methyl methaoate → methanoic acid + methanol
For example: methyl ethanoate will be an isomer of ethyl methanoate since the both have the same molecular formula: C2H6O2
What would be an isomer of ethyl propanoate, for instance?
