Which of the following carboxylic acids undergoes decarboxylation easily? Explain briefly.
Answers
Just more complicated
Answer:
(i) C6H5-CO-CH2-COOH is the correct answer.
Explanation:
Carboxylic acids are inorganic compounds.
They are main compounds used for preparation of esters, acid chlorides and amides.
Their functional group is COOH.
When anhydrous sodium salt of carboxylic acid is fused with soda lime, it gives hydrocarbon containing one carbon atom less than carboxylic acid.
Soda line is sodium hydroxide and calcium oxide in the ratio of 3:1.
This is decarboxylation.
The decarboxylation of acids depend upon stability of carbanion.
Among the following anions, C6H5-CO-CH2-COOH is most stable carbanion.
It can underground decarboxylation very easily as compared to the other carbanions.
Hence,
(i) C6H5-CO-CH2-COOH is the correct answer
