$n-Butylamine$ $>$ $Diethylamine$ $>$ $Ethyl$ dimethylamine

Vedclass · Answer

(D) The boiling point of amines depends on the extent of intermolecular hydrogen bonding. Primary amines $(R-NH_2)$ have two hydrogen atoms available for hydrogen bonding,secondary amines $(R_2NH)$ have one,and tertiary amines $(R_3N)$ have none. Therefore,the general order of boiling points is $1^{\circ} > 2^{\circ} > 3^{\circ}$ for isomeric amines. $n-Butylamine$ $(1^{\circ})$ has the highest boiling point,followed by $Diethylamine$ $(2^{\circ})$,and $Ethyl$ dimethylamine $(3^{\circ})$ has the lowest. The correct order is $n-Butylamine > Diethylamine > Ethyl$ dimethylamine.

Which among the following decreasing order of boiling points is correct for amines?
