Question

Describe a chemical test to distinguish an alcohol and carboxylic acid group

Answer 1

(i)Litmus test – Alcohol will have no effect on the litmus paper. Carboxylic acid acid will change blue litmus paper into red.

(ii)Reaction with sodium hydrogen carbonate – Alcohol has no reaction with sodium hydrogen carbonate (NaHCO3) but in the case of Carboxylic acid it reacts with NaHCO3 which gives CH3COONa, CO2 and H2O. The reaction is evident as the carbon dioxide will turn the lime water milky.
