Draw illustrations to show how water forms hydrogen bond with ethanol.

Hydrogen bonding is responsible for the solubility of low molecular weight alcohols such as ethanol in water.

Explanation:

Hydrogen bond is an interaction formed between hydrogen and a highly electronegative element such as oxygen, fluorine, chlorine, nitrogen, sulphur, etc. Hydrogen bond occurs due to a permanent dipole interaction between hydrogen and the highly electronegative element. Hydrogen bond is responsible for the solubility of low molecular weight alcohols in water.

The alcohol interacts with water via hydrogen bonding as shown in the image attached. This ensures the solubility of the low molecular weight alcohols in water.

Ethanol interacts effectively with water via hydrogen bonding as shown in the image attached to this answer.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
