Which of the following compounds has lowest boiling point?

Options

  1. AChloromethane
  2. BFluoromethane
  3. CIodomethane
  4. DBromomethane

Correct answer

B. Fluoromethane

Step-by-step solution

For a given alkyl group, the boiling point increases with increasing atomic mass of halogen. Hence, boiling point of the given alkyl halides decreases in the order: CH ₃ I > CH ₃ Br > CH ₃ Cl > CH ₃ ~F
