The boiling points of ethyl alcohol and water are $78°\mathit{C\; and }100°\mathit{C }$ respectively. From these two liquids which one has the interparticle forces of attraction stronger?

The interparticle forces of attraction are stronger in water as compared to ethyl alcohol.

The boiling point of a liquid is determined by the strength of the intermolecular forces present in that liquid. Water has a strong bonding between its molecules. This creates relatively strong forces that require more energy to break, resulting in a higher boiling point of 100°C.

On the other hand, ethyl alcohol has weaker intermolecular forces compared to water. As a result, ethanol has a lower boiling point of 78°C.
