Butan-1-amine has higher boiling point than N-ethylethanamine.

Question

Give a plausible explanation for each of the
following statements :

Butan-1-amine has higher boiling point than N-ethylethanamine.

Answer 1

Due to the presence of two H-atoms on N-atom in butain- 1-amine, they undergo extensive intermolecular H-bonding while in N-cthylethanamine due to the presence of one-H atom on the N-atom, they undergo least intermolecular H-bonding. 

Hence,

Butan-1-amine has higher boiling point than-N-ethyl ethanamine.
