Unusual Properties of Water (textbook 5.5)

Chemical Ideas 5.5

Hydrogen bonding in water is strong due to 2 lone pairs of electrons and two positively charged hydrogen atoms per oxygen atom, so intermolecular bonds are maximised

Water in comparison to similar compounds (of lower molecular mass)

High values of boiling point and enthalpy change of vapourisation

• enthalpy change of vapourisation - a measure of the energy put into a liquid to overcome the intermolecular bonds and…
