Question
Arrange the following compounds according to increasing order of boiling points.
$n - C_{4}H_{9}OH(A),n - C_{4}H_{9}{NH}_{2}(\text{ }B)$, $n - C_{4}H_{10}(C)$ and $C_{2}H_{5}{NHC}_{2}H_{5}(D)$.
Options
A.C $<$ B $<$ A $<$ D
B.D $<$ C $<$ B $<$ A
C.C $<$ D $<$ B $<$ A
D.D $<$ B $<$ A $<$ C
Solution
Sol. [Key Concept: Boiling point rises with hydrogen-bonding capacity: alkane $<$ secondary amine $<$ primary amine $<$ alcohol, i.e. $C < D < B < A$.]
Boiling point $\propto$ Intermolecular attraction
œ Number of H-bonding
n-butanol has strong H-bonding.
