Question 1:
How would you distinguish experimentally between an alcohol and a carboxylic acid?
Answer:
We can distinguish between an alcohol and a carboxylic acid on the basis of their reaction with carbonates and hydrogen carbonates. Acid reacts with carbonate and hydrogen carbonate to evolve CO2 gas that turns lime water milky.
Alcohols, on the other hand, do not react with carbonates and hydrogen carbonates.
Question 2:
What are oxidising agents?
Answer:
Some substances such as alkaline potassium permanganate and acidified potassium dichromate are capable of adding oxygen to others. These are known as oxidising agents.
