The correct order of boiling points of following molecules is
(i) n-Hexane
(ii) 2-methylpentane
(iii) 2,3-dimethylbutane
- A i \(>\) ii \(>\) iii
- B iii \(>\) ii \(>\) i
- C iii \(>\) i \(>\) ii
- D i \(>\) iii \(>\) ii
Answer & Solution
Correct Answer
(A) i \(>\) ii \(>\) iii
Step-by-step Solution
Detailed explanation
(Boiling point of isomeric alkanes decreases with increasing branching due to a decrease in the exposed surface area that leads to weaker van der Waal forces. Thus, the order will be :-
