1.1. This question is about the boiling points of organic compounds.

The boiling points of three organic compounds are shown in Table 1.

Table 1

i) Suggest why the three organic compounds might be expected to have similar boiling points.

ii) Explain why the three organic compounds do not have similar boiling points.

1.2. Suggest a value for the boiling point of propanone. Justify your answer.

1.3. Explain why there are no hydrogen bonds between propanone molecules, even though propanone forms hydrogen bonds in water.

1.4. Describe one test tube reaction that could be used to distinguish between samples of propanal and propanone.
