An organic acid 'z' reacts separately with sodium bicarbonate, sodium hydroxide and sodium carbonate. Which one of the following represent the structure of 'z'?
Correct answer: D. H3C―CH2―COOH
- A. HCOOC2H5
- B. CH3―CH=CH2
- C. CH3CH2OH
- D. H3C―CH2―COOH
Explanation
H3C―CH2―COOH: This structure represents propanoic acid, which is an organic acid. The carboxylic acid functional group (-COOH) is present in this structure, which is characteristic of organic acids. Therefore, this option represents the correct structure of 'z'.

About Carboxylic Acids
Carboxylic acids are named and studied through the combined effects of the carbonyl and hydroxyl groups, their preparation, acidity and hydrogen bonding. Reactions include neutralisation, esterification, reduction and conversion into acid chlorides, anhydrides, esters and amides, with emphasis on how these derivatives interconvert.
