Question
Melting points are normally the highest for
- Tertiary amides
- Secondary amides
- Primary amides
- Amines
The correct answer is: Primary amides
The higher boiling points of amide is because of Intermolecular hydrogen bonding
Due to intermolecular hydrogen bonding they have high boiling point than amine and amongst amide the order of Boiling point are
Primary Sec Tertiary
This is because of alkyl group by which the carbonyl oxygen do not form the hydrogen bond (other molecule) so primary amide have high boiling point and Tertiary amides does not have to form bond with O of other amide and have least B.P
