The reaction CHCH + H2O + 3(O) shows the formation of _.

Correct answer: C. Oxalic acid

  • A. Acetic acid
  • B. Picric acid
  • C. Oxalic acid
  • D. Formic acid

Explanation

For this question, we must assume CHCH to be ethyne. The (O) implies oxidation and water indicates that the oxidizing agent is dilute. Based on that we would be getting CHOHCHOH as an intermediate as hydroxyl groups are added to each carbon. This is similar to how we obtain diols from alkenes by oxidizing them through dilute potassium manganate. Further oxidation takes place and since we have 2 aldehyde groups, each is oxidized to give a carboxylic acid thus 2 carboxylic acid groups which is Oxalic acid.

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.
