Question 4
The graph shows the boiling points of the hydrogen compounds of Group 16 elements.
Which statement correctly explains why water does not fit the trend of the other compounds?
A
There are fewer electrons in the oxygen atoms so there is less shielding of the nuclear charge.
B
There are strong hydrogen bonds in water but not in the other compounds.
C
The covalent bonds in water are much stronger than in the other compounds.
D
The water molecules are smaller and so have stronger van der Waals' forces.
