Question
Which of the following can damage optic nerve leading to blindness, if taken internally?
(a) CH3COOH
(b) C2H5OH
(c) NaHCO3
(d) CH3OH

Solution
CH3OH
CH3OH (methanol), when consumed, oxidises into methanal into the liver. This causes coagulation of protoplasm in the cells, as methanal reacts rapidly with the components of the cells. Due to this, the cells stop functioning and damage the optic nerve leading to blindness.
