MHT CET · Chemistry · Haloalkanes and Haloarenes
Which among the following has lowest boiling point?
- A Chloromethane
- B Fluoromethane
- C Bromomethane
- D Iodomethane
Answer & Solution
Correct Answer
(B) Fluoromethane
Step-by-step Solution
Detailed explanation
Boiling points (B.P.) of the halogen derivatives depends upon the molecular size. In given case, all compounds contain only one carbon atom, thus B.P. depends upon size of halogen present. As F has lowest size, so fluoromethane will have lowest B.P.
