Carboxyic acids esters and amides are all polar compounds Ony carboxylic acids and 1 and 2 amides can undergo intermolecular hydrogen bonding ii iii 0 I in C9 H hi i H CH3 RH e hydidgeniigiond Carboxyic acids have higher boiling points than similar alcohols because there are more hydrogen bonding interactions possible than alcohols 1 and 2 amides have higher boiling points than 3 amides and esters This is because of the intermolecular hydrogen bonding within 1 and 2 0 Strongest intermolecular forces highest boiling point 174 Interesting Carboxylic Acids Simpe carboxylic acids have foul
