Question: The compound used as antifreeze in car radiators in cold regions of the world is?

The compound commonly used as an antifreeze in car radiators in cold regions of the world is ethylene glycol (C2H6O2). Ethylene glycol has a very low freezing point, which makes it an effective antifreeze for use in car radiators. It works by lowering the freezing point of water in the radiator, preventing the water from freezing and expanding, which can cause damage to the radiator and engine block. Ethylene glycol is also used as a coolant in other applications, such as in refrigeration systems and air conditioning units. However, it is important to handle ethylene glycol with care, as it is toxic if ingested and can be harmful to the environment if not disposed of properly.
