(ii) The diagram shows three water molecules. Complete the diagram to show a hydrogen bond between two water molecules.

Answer:

An explanation that includes the following points:
- the oxygen (atom) is slightly negative and the hydrogens (atoms) are slightly positive\} (1)
- \{there is (an uneven) charge distribution (across the molecule) / uneven distribution of electrons / the oxygen pulls the electrons towards it\} (1)
- a line drawn between an O of one molecule and a H of another molecule (1)
