Arrange the given set of compounds in order of increasing boiling point: I. 1-chloropropane II. Isopropyl chloride III. 1-chlorobutane

A$$II < III < I$$
B$$I < II < III$$
C$$II < I < III$$
Correct Answer
D$$III < I < III$$

Solution

Alkyl halides containing same halide, the boiling point increases with increase in alkyl chain. So 1-chlorobutane is having more boiling point than 1-chloro propane. Also the boiling point decreases with increase in branching in the chain. So the boiling point of 1-chloropropane is greater than isopropyl chloride. Hence the correct order of boiling points is:
$$Isopropyl chloride<1-chloro propane<1-chloro butane$$.
Hence option C is correct.
