They do not possess inter-molecular $H$-bonding

Vedclass · Answer

(D) $1$. Primary $(R-NH_2)$ and secondary $(R_2NH)$ amines contain $N-H$ bonds, which allow for inter-molecular hydrogen bonding.$2$. Tertiary amines $(R_3N)$ do not have any hydrogen atoms attached to the nitrogen atom.$3$. Due to the absence of $N-H$ bonds, tertiary amines cannot form inter-molecular hydrogen bonds.$4$. Consequently, they have weaker inter-molecular forces compared to primary and secondary amines, resulting in lower boiling points.

Tertiary amines have the lowest boiling points among isomeric amines because,
