The boiling point of ethanol is- A. 180°C B. 58°C C. 98°C D. 78°C

The correct answer is D. 78°C.

Ethanol is a colorless, flammable liquid with a characteristic odor. It is the alcohol found in alcoholic beverages and is also used as a solvent, fuel, and in the production of other chemicals. Ethanol has a boiling point of 78°C, which is lower than the boiling point of water (100°C). This means that ethanol will vaporize at a lower temperature than water. This property of ethanol is used in the production of alcoholic beverages, as well as in the production of other chemicals.

Option A is incorrect because the boiling point of ethanol is 78°C, not 180°C.

Option B is incorrect because the boiling point of ethanol is 78°C, not 58°C.

Option C is incorrect because the boiling point of ethanol is 78°C, not 98°C.
