Which has a higher boiling point: ether, aldehyde, alkane, or alcohol?

Answer 1

Alcohol, due to strongest intermolecular forces of attraction between molecules. (assuming similar lengths of carbon chains in each compound).

However, as the carbon chain length increases, the molecules all get bigger, so this can also effect the strength of the intermolecular forces and hence the relative boiling points. Assuming similar lengths of carbon chains of each, alcohol will have the highest boiling point due to the presence of strong hydrogen bonds as intermolecular forces holding particles together.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
