Which of the following compounds has the highest boiling point?

A$$CH_3CH_2CH_2Cl$$
B$$CH_3CH_2CH_2CH_2Cl$$
Correct Answer
C$$CH_3CH(CH_3)CH_2Cl$$
D$$(CH_3)_3CCl$$

Solution

For the same halogen, boiling point of alkyl halide decreases as the size of the alkyl group decreases. For isomeric alkyl halides, boiling point decreases as branching increases. So the decreasing order of boiling point is
$$CH_3CH_2CH_2CH_2Cl > CH_3CH_2CH_2Cl > CH_3CH(CH_3)CH_2Cl > (CH_3)_3CCl$$

Hence, Option "B" is the correct answer.
