Question Discussion & Solution

The correct answer is Esterification.

Key Points

• Esterification -
  • Acid + Alcohol = Ester
  • It is a chemical reaction that forms at least one ester.
  • Esters are produced when acids are heated with alcohol.

Additional Information

• Crystallization -
  • The process of obtaining a pure solid in the form of crystals from a saturated solution is called crystallization.
  • In crystallization, the solution is first evaporated to separate a solid from the solution.
  • When the solution becomes very concentrated, the solution is cooled slowly by stopping evaporation, causing crystals to form.
• Saponification -
  • The saponification of a fat or oil is done by using NaOH solution for the hot process.
  • Saponification to the sodium salt of myristic acid takes place with NaOH in water.
  • Soap is formed by a chemical reaction by heating an aqueous solution of vegetable oil or fat and caustic soda or caustic potash, and glycerol is liberated.
