Give plausible explanation for the following statement: Why do primary amines have higher boiling point than tertiary amines?

Options

  1. ABecause in primary amines, Nitrogen atoms have two Hydrogen atoms which result in extensive intermolecular H -
  2. BTertiary amines have a larger molecular mass than primary amines, leading to higher boiling points.
  3. CPrimary amines have a more complex molecular structure than tertiary amines, resulting in stronger van der Waa
  4. DTertiary amines have a higher electron density on the nitrogen atom, which leads to increased boiling points.

Correct answer

A. Because in primary amines, Nitrogen atoms have two Hydrogen atoms which result in extensive intermolecular H -

Step-by-step solution

Correct Option is : (A) Because in primary amines, Nitrogen atoms have two Hydrogen atoms which result in extensive intermolecular H - bonding while in tertiary amines, Nitrogen atoms do not have any Hydrogen atoms and hydrogen bonding is not possible.
