Structural formula for the saponification acidification and decarboxylation product of β-ketoester diethyl 2-methyl-3-oxosuccinate 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. 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.

Question

Definition Definition Class of organic compounds that contain a carboxyl group ( - COOH ) and has a general formula R - COOH or R - CO 2 H , where R refers to the alkyl, alkenyl, aryl, or other groups. They can undergo different chemical reactions, such as acid-base reactions, esterification, and oxidation. These are essential components of living organisms, playing important roles in metabolic processes, signaling, and as pharmaceuticals.

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.

Draw the titration curve of (i) weak acid vs. strong base; (ii) weak acid vs. weakbase; (iii) diprotic acid with strong base (iii) triprotic acid with strong base.

Complete the reaction in the drawing area below by adding the major products to the right-hand side. If there won't be any products, because nothing will happen under these reaction conditions, check the box under the drawing area instead. Note: if the products contain one or more pairs of enantiomers, don't worry about drawing each enantiomer with dash and wedge bonds. Just draw one molecule to represent each pair of enantiomers, using line bonds at the chiral center. More... No reaction. my ㄖˋ + 1. Na O Me Click and drag to start drawing a structure. 2. H +
