JEE Main 2025 — 22 January, Evening Shift — Question 26

Arrange the following compounds in increasing order of their dipole moment :

$\mathrm{HBr}, \mathrm{H}_{2} \mathrm{~S}, \mathrm{NF}_{3}$ and $\mathrm{CHCl}_{3}$

Option A:
$\mathrm{NF}_{3}<\mathrm{HBr}<\mathrm{H}_{2} \mathrm{~S}<\mathrm{CHCl}_{3}$
Correct
Option B:
$\mathrm{HBr}<\mathrm{H}_{2} \mathrm{~S}<\mathrm{NF}_{3}<\mathrm{CHCl}_{3}$
Option C:
$\mathrm{H}_{2} \mathrm{~S}<\mathrm{HBr}<\mathrm{NF}_{3}<\mathrm{CHCl}_{3}$
Option D:
$\mathrm{CHCl}_{3}<\mathrm{NF}_{3}<\mathrm{HBr}<\mathrm{H}_{2} \mathrm{~S}$

Answer: A

Increasing order of Dipole moment

\begin{array}{r} \mathrm{NF}_{3}<\mathrm{HBr}<\mathrm{H}_{2} \mathrm{~S}<\mathrm{CHCl}_{3}\end{array}
