Which of the following compounds has highest boiling point?
- A Chloromethane
- B Fluoromethane
- C Iodomethane
- D Bromomethane
Answer & Solution
Correct Answer
(C) Iodomethane
Step-by-step Solution
Detailed explanation
Molecules with higher molecular mass have higher boiling points.
So, for given alkyl group \(\left(-\mathrm{CH}_3\right)\) boiling point decreases as, \(\mathrm{CH}_3 \mathrm{I}>\mathrm{CH}_3 \mathrm{Br}>\mathrm{CH}_3 \mathrm{Cl}>\mathrm{CH}_3 \mathrm{~F}\).
So, for given alkyl group \(\left(-\mathrm{CH}_3\right)\) boiling point decreases as, \(\mathrm{CH}_3 \mathrm{I}>\mathrm{CH}_3 \mathrm{Br}>\mathrm{CH}_3 \mathrm{Cl}>\mathrm{CH}_3 \mathrm{~F}\).
