Question

Which best explains why water has a much higher boiling point than would otherwise be predicted?
Water forms weak hydrogen bonds.
Water forms strong hydrogen bonds.
Water has weak cohesive forces.
Water has strong adhesive forces.

Answer 1

Water forms strong hydrogen bonds.

These intermolecular H‑bonds between H of one water and the O of another require extra energy to break, so water's boiling point is much higher than predicted from molecular weight alone.
