JEE Main 2026 — 6 April, Morning Shift — Question 60

Arrange the following compounds according to increasing order of boiling points. $\mathrm{n}-\mathrm{C}_{4} \mathrm{H}_{9} \mathrm{OH}(\mathrm{A}), \mathrm{n}-\mathrm{C}_{4} \mathrm{H}_{9} \mathrm{NH}_{2}(\mathrm{~B})$ , $\mathrm{n}-\mathrm{C}_{4} \mathrm{H}_{10}(\mathrm{C})$ and $\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{NHC}_{2} \mathrm{H}_{5}(\mathrm{D})$ .

Option A:
$\mathrm{C}<\mathrm{B}<\mathrm{A}<\mathrm{D}$
Option B:
D $<$ C $<$ B $<$ A
Option C:
C $<$ D $<$ B $<$ A
Correct
Option D:
D $<$ B $<$ A $<$ C

Answer: C
