Explain why, methanol is much more dangerous to drink than ethanol.

उत्तर
Methanol is a poison when taken internally. Though both methanol and ethanol are metabolised by the liver, the rate of metabolism differs. Methanol gets oxidised to methanal in the liver, which rapidly reacts with the cell components and causes coagulation of protoplasm. As a result, the cells stop functioning causing death of the person who consumes methanol.
