Which compound below can be used as the antifreeze in cars radiators by mixing with water?

The best compound that can be used as an antifreeze in a car radiator by mixing with water is ethylene glycol. It is a colorless, odorless, and sweet-tasting liquid that has a freezing point of -12.9 degrees Celsius and a boiling point of 197.4 degrees Celsius. When mixed with water, ethylene glycol forms a solution that has a lower freezing point and a higher boiling point than water alone. This makes it ideal for use as an antifreeze in car radiators, as it prevents the water from freezing in cold weather and from boiling in hot weather. Ethylene glycol also has lubricating properties, which helps to protect the water pump and other components of the car's cooling system. However, it is important to note that ethylene glycol is toxic and should be handled with care.
