2b(iv) Consider the compounds with the following structures: S—H···N and O—H···N. In which of the compounds is the hydrogen bond stronger? Give reason for your answer.

The hydrogen bond is stronger in O—H···N. This is because oxygen is smaller and more electronegative than sulphur, so O-H forms a stronger hydrogen bond.
