The graph presents the boiling points of the hydrogen compounds of Group 16 elements. Which statement gives the correct explanation for why water does not follow the pattern shown by the other compounds?
- AThere are fewer electrons in the oxygen atoms so there is less shielding of the nuclear charge.
- BThere are strong hydrogen bonds in water but not in the other compounds.
- CThe covalent bonds in water are much stronger than in the other compounds.
- DThe water molecules are smaller and so have stronger van der Waals' forces.
