JEE Main Chemistry question

In a group of isomeric alkyl halides, the order of boiling points is

(A)primary < secondary < tertiary
(B)primary > secondary > tertiaryCorrect
(C)primary < secondary > tertiary
(D)primary > secondary < tertiary

Answer: (B)

Solution

Among isomeric alkyl halides, increased branching (going from primary to secondary to tertiary) makes the molecule more compact and spherical, reducing its surface area and hence the strength of intermolecular van der
