Which of the following are arranged in the decreasing order of dipole moment?
Options
- A
- B
- C
- D
Correct answer
B.
Step-by-step solution
The values of dipole moments of methyl halides:
\begin{aligned} \mathrm{CH}_{3} \mathrm{ F}-1.51 \mathrm{D}; \mathrm{CH}_{3} \mathrm{Cl}-1.56 \mathrm{D}; \\
\mathrm{CH}_{3} \mathrm{Br}-1.4 \mathrm{D}; \mathrm{CH}_{3} \mathrm{I}-1.29 \mathrm{D}\\
& \therefore \quad \mathrm{CH}_{3} \mathrm{Cl}> \mathrm{CH} }_{3} \mathrm{ F}>\mathrm{CH}_{3} \mathrm{Br} > \mathrm{CH} }_{3} \mathrm{I}.
\end{aligned}
