New cards

How are esters produced?

Condensation reaction between alcohol and Carboxylic acid

2
New cards

Explain the condensation reaction

Between alcohol and carboxylic acid with conc H2SO4

3
New cards

Describe acid hydrolysis of esters

  • When an ester is heated under reflux with dilute acid an equilibrium mixture is established as the reaction is reversible

4
New cards

Describe alkaline hydrolysis of esters

  • heating the ester under reflux with dilute alkali is an irreversible reaction as the ester is fully hydrolysed

  • This results in the formation of a sodium carboxylate salt which needs further acidification to turn into a carboxylic acid
