Ethanol is an organic compound that contains a hydroxyl group as a functional group.
Ethanol is a clear colourless liquid.
Solubility of ethanol in water:
Ethanol has a hydroxyl(-OH) functional group in it.
Due to the presence of a bond between electronegative atom oxygen and hydrogen, the O-H bond acquires polarity.
Hence, due to the presence of polarity in O-H bond, it forms a Hydrogen bond with water which is responsible for the responsibility of ethanol in water.
