Q1: Liquor poisoning generally occurs due to the presence of __________ in it.

ANS:C - methyl alcohol

Liquor poisoning generally occurs due to the presence of methyl alcohol in it. Methyl alcohol, also known as methanol, is a toxic compound that can be found in certain alcoholic beverages, particularly in illicit or poorly regulated products. Ingesting methanol can lead to severe health complications and even death. Methanol is metabolized in the body into toxic byproducts such as formaldehyde and formic acid, which can cause metabolic acidosis, central nervous system depression, blindness, and organ damage. It's important to note that while ethyl alcohol (ethanol) is the primary psychoactive ingredient in alcoholic beverages and is safe for consumption in moderate amounts, consuming methanol, either intentionally or unintentionally, can have serious and potentially fatal consequences. Impurities in alcoholic beverages can also contribute to liquor poisoning, but methyl alcohol is specifically known for its toxicity and potential to cause harm.
