2.3. ethanol(common alcohol) is a compound
with a melting point of -114°c and boiling
point of 78°c. what is it's physical state at
room temperature 20°c?

At 20°C, Ethanol (not common alcohol) is in a liquid state.

Explanation:

At 20°C (degrees Centigrade/Celsius), ethanol is above the point it goes solid, so it may not be solid. However, it is below 78°C, so it is not a gas nor is it plasma. Therefore, it is in the liquid state.

Ethyl Alcohol is known for use in drinking, Isopropyl Alcohol is known to be a common disinfectant, and Ethanol is known for use in car fuel. Therefore, there is no common alcohol; many forms of alcohol have everyday uses.
