Give Preparation of sponification reaction and esterification reaction
Answers
Answer:
Explanation:Saponification is a process by which triglycerides are reacted with sodium or potassium hydroxide (lye) to produce glycerol and a fatty acid salt, called "soap." The triglycerides are most often animal fats or vegetable oils. When sodium hydroxide is used, a hard soap is produced. Using potassium hydroxide results in a soft soap.
Saponification Example
In saponification, a fat reacts with a base to form glycerol and soap.
In saponification, a fat reacts with a base to form glycerol and soap. Todd Helmenstine
Lipids that contain fatty acid ester linkages can undergo hydrolysis. This reaction is catalyzed by a strong acid or base. Saponification is the alkaline hydrolysis of the fatty acid esters. The mechanism of saponification is:
Nucleophilic attack by the hydroxide
Leaving group removal
Deprotonation
The chemical reaction between any fat and sodium hydroxide is a saponification reaction.
triglyceride + sodium hydroxide (or potassium hydroxide) → glycerol + 3 soap molecules
Key Takeaways: Saponification
Saponification is the name of the chemical reaction that produces soap.
In the process, animal or vegetable fat is converted into soap (a fatty acid) and alcohol. The reaction requires a solution of an alkali (e.g., sodium hydroxide or potassium hydroxide) in water and also heat.
The reaction is used commercially to make soap, lubricants, and fire extinguishers.
