give reasons :
1. aromatic carboxylic acid is stronger than aliphatic carboxylic acid .
2. primary amines have higher boiling point than tertiary amines .

Solution

Primary amines have an extensive amount of hydrogen bonding as compared to tertiary amines. Therefore higher amount of energy is required to break these bonds and therefore boiling points of primary amines are higher than tertiary amines.
