Boiling points of carbonyl compounds lie between the parent alkanes and correponding alcohols. Justify.

Explanation

Alkanes are non-polar in nature and the attractive forces are weak van der Waals' forces. In alcohols, intermolecular hydrogen bonding is present in the molecules. In the carbonyl compounds, only dipolar forces exist in the molecules. It is therefore, quite obvious that the attractive forces in carbonyl compounds are more than in alkanes and less in comparison to alcohols. This justifies the trend the trend in boiling point values in the members of these families.
