If water and ethanol both have all three intermolecular bonds, why does ethanol evaporate so much quicker?
Answer (2)
Many alcohols like ethanol have low boiling points, lower than water. Because of this, the ethanol molecules can overcome their inter molecular bonds that hold them in that liquid state. Hope this helps :)
Ethanol evaporates faster than water primarily due to its lower boiling point and weaker intermolecular forces. Although both substances can engage in hydrogen bonding, the stronger hydrogen bonds in water make it less volatile. Therefore, ethanol molecules require less energy to escape into the vapor phase.
