Give plausible explanation for each of the following :
Why do primary amines have higher boiling points than tertiary amines ?

Text Solution

Verified by Experts

Due to the presence of two H-atoms on N-atom of primary amines, they undergo extensive intermolecular H-bonding resulting in association while tertiary amines due to the absence of a H-atom on the N-atom, do not undergo H-bonding. As a result, primary amines have higher boiling points than tertiary amines of comparable molecular masses.
