Chemical bonding... Hydrogen bond in water is resopnsible for higher heating value.. In ethanol hydrogen bonding is not that strong

Hydrogen bonding is stronger in water than in ethanol. Positive H complements the negative electron pairs in O and, thus, forming a stronger intermolecular force. Water needs higher energy to break those bonds. Hence, water has higher boiling point at same atmospheric pressure than ethanol.
