Question

Write short note on Preparation of alcohols by fermentation method.

Answer 1

Explanation:

Fermentation is the slow decomposition of complex organic compounds into simpler organic compounds by the activity of enzymes. Enzymes are complex, nitrogenous (proteins), non-living macromolecules of high molecular weight. We usually get these enzymes from living organisms.

This process is usually followed by the evolution of gases like CO2 & CH4. They release a lot of energy and are exothermic in nature. The alcoholic fermentation involves the conversion of sugar into ethyl alcohol by yeast.
