Question

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

Answer 1

Compound A is
Ethanol(C2H5OH) as it is the constituent of antifreeze. When Oxygen is reacted with ethanol then acetic acid and water is released.But directly ethanol can not be reacted to obtain acetic acid.In this reaction an aldehyde is firmed and then acetic acid is formed .

Answer 2

Answer:

A is Ethanol and B is Ethanoic Acid

Explanation:

The compound 'A' is ethanol and with alkaline KMnO4, it is oxidised to ethanoic acid 'B'.
