Question

Which of the following should be most volatile?

Options

  • \[\ce{(CH3)3N}\]

  •  \[\ce{CH3CH2CH3}\]

  • \[\ce{CH3CH2CH2NH2}\]

  • \[\begin{array}{cc}
    \ce{CH3CH2}\\
    \phantom{..........}\backslash\\
    \phantom{...............}\ce{NH}\\
    \phantom{...........}/\\\
    \phantom{......}\ce{CH3}
    \end{array}\]

Solution

 \[\ce{CH3CH2CH3}\]

Explanation:

Among primary, secondary and tertiary amines, tertiary amines are the most volatile compounds as they don't have any strong intermolecular H - bonding between \[\ce{N - H}\] like the primary and secondary amines have.
