Read the passage given below and answer the following questions:
Alkyl/Aryl halides may be classified as mono, di or polyhalogen compounds depending on one, two or more halogen atoms in their structures. Alkyl halides are prepared by free radical halogenation of alkanes, addition of halogen acids to alkenes and replacement of -OH group of alcohols with halogens using phosphorus halides, thionyl chloride or halogen acids. Aryl halides are prepared by electrophilic substitution to arenes.
The following questions are multiple choice questions.
Choose the most appropriate answer:
Arrange the following compounds in increasing order of their boiling points.
(i)

Options

A. `ii lt iii lt i`
B. `i lt ii lt iii`
C. `iii lt i lt ii`
D. `iii lt ii lt i`

Answer

C

Explanation

Boiling point of (i) is 364 K, boiling point of (ii) is 375 K. boiling point of (iii) is 346 K As the branching increases in the isomeric alkyl halides, the boiling point decreases.
