Question

6. An organic compound ‘A’ is a constituent of antifreeze. The compound on heating with oxygen
forms another compound ‘B’ which has a molecular formula C2H4O2. Identify the compound ‘A’
and ‘B’. Write the chemical equation of the reaction to form the compound ‘B’.

Solution

Compound 'A' is ethanol 'C ₂H₅OH'
Compound 'B' is ethanoic acid 'CH ₃COOH' which can be also write as C₂H₄O₂
B cannot be aldehyde because final oxidation product is carboxylic acid but if oxidation is carried out in presence of some mild oxidising agent, then it may results aldehyde.
C₂H₅OH + O₂(strong oxidising agent) ------> CH₃COOH + H₂O
C₂H₅OH + O₂(weak/mild oxidising agent, PCC) ------> CH₃CHO + H₂O
