Concept Introduction:
Saponification:
It is a process in which triglycerides reacts with sodium or potassium hydroxide to form fatty acids and glycerol. This reaction is also known as alkaline hydrolysis of ester.
Decarboxylation:
It is a reaction which involves the release of carbondioxide by removing the carboxyl group. This also involves the removal of carbon atom from the chain.

Concept Introduction:
Saponification:
It is a process in which triglycerides reacts with sodium or potassium hydroxide to form fatty acids and glycerol. This reaction is also known as alkaline hydrolysis of ester. Saponification is mainly used for manufacturing soap.
Decarboxylation:
It is a reaction which involves the release of carbondioxide by removing the carboxyl group. This also involes the removal of carbon atom from the carbonchain. Enzymes which catalyze decarboxylation are known as decarboxylase. Alkanoic acid decarboxylation is very slow.
(c)
Interpretation:
Structural formula for the saponification acidification and decarboxylation product of ethyl 2-methyl-3-oxopropanoate has to be drawn.
Concept Introduction:
Saponification:
It is a process in which triglycerides reacts with sodium or potassium hydroxide to form fatty acids and glycerol. In simple saponification is a reaction between an acid and a base to form salt. The base commonly used is sodium hydroxide. Potassium hydroxide is also used. This reaction is also known as alkaline hydrolysis of ester.
Decarboxylation:
It is a reaction which erases a carbon atom from the carbon chain by releasing carbondioxide. It is a unimolecular dissociative process that gives a carbanion and carbondioxide.
