Consumption of which of the following even in small dose causes blindness and may prove fall ?

Options

A. Methyl alcohol
B. Methanol
C. Carbinol
D. All of these

Answer

D

Explanation

Biological oxidation of methanol and ethanol in the body produces the corresponding aldehyde followed by the acid. At times the alcoholics , by mistake , drink ethanol, mixed with methanol also called denatured alcohol.
In the body , methanol is oxidized first to methanol and then to methanoic acid, which may cause blindness and death. A methanol poisoned patient is treated by giving intravenous infusions of diluted ethanol. The enzyme responsible for oxidation of `HCHO to HCO_(2)H` is swamped allowing time for kidneys to excrete methanol.
