Removal of CO2 is called_____________________?
Correct answer: B. decarboxylation
- A. carboxylation
- B. decarboxylation
- C. esterification
- D. hydroxylation
Explanation
Decarboxylation is the removal of carbon dioxide, CO2, from a carboxylic acid or its salt, often on heating with soda lime. A student may choose carboxylation because it contains the word carboxyl, but carboxylation means adding CO2 rather than removing it.

About Nomenclature, Structure and Preparation
Carboxylic acids are prepared by oxidising primary alcohols or aldehydes, hydrolysing nitriles, esters and amides, and carbonating suitable organometallic compounds. Their structures, IUPAC naming, resonance stabilisation and acidic character explain why carboxylic acids differ from alcohols and phenols, despite all containing oxygen and hydrogen.
