Which of the following is not a property of water?
Hydrogen bonding causes a high surface tension.
Hydrogen bonds exist only in the solid state.
Water can dissolve ionic and polar molecules.
Water's solid state is less dense than its liquid state.

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.
