How do you distinguish experimentally between an alcohol and a carboxylic acid ?

Text Solution

Verified by Experts

The formula for cyclopentane is `C_5 H_(10)` . Its electron dot structure is given below.

We can distinguish betwecn an alcohol and a carboxylic acid on the basis of their reaction with carbonate and hydrogen carbonates. Acids reacts with carbonate and hydrogen carbonate to evolve `CO_2` gas that turms lime water milky.
Metal carbonate / metal hydrogen carbonate + carboxylic acid.
`" " darr`
Salt + water + carbondioxide .
Alcohols on the other hand, do not react with carbonates and hydrogen carbonates.
