Question

Which of the following alkyl halides has the lowest boiling point?

Options

• \[\ce{CH3 - CH2 - Br}\]

• \[\ce{CH3 - (CH2)2 - CH2Br}\]

• \[\ce{CH3 - CH2 - CH2 - Br}\]

• \[\ce{CH3Br}\]

Answer 1

\[\ce{CH3Br}\]

Explanation:

If the halogen atom is the same, the physical qualities are determined by the type of the alkyl chain. The boiling point of the same halogen atom rises as the molecular weight rises. As a result, the lowest boiling point is CH₃Br.
