A colorless, odorless, and poisonous gas produced by tobacco burning is called?

Explanation:
Carbon monoxide is the colorless, odorless, poisonous gas produced when tobacco is burned. It enters the lungs with smoke and binds strongly to hemoglobin in red blood cells, forming carboxyhemoglobin, which reduces the blood’s capacity to carry oxygen to tissues. This hidden depletion of oxygen can strain the heart and brain, making CO exposure particularly dangerous because you can’t detect it by smell or taste. Tar, by contrast, is a sticky solid residue that coats the lungs; leukoplakia is a precancerous mouth lesion; smokeless tobacco is used without burning. So the gas described is carbon monoxide.
