NEET Chemistry (general) MCQ Question
Type: MCQ-numerical-Hard-Class 11
If the boiling point of n-butane is 273 K, what is the boiling point of the isomer with a branched chain of C4H10, considering that branching generally decreases boiling points?
A
267 K
B
273 K
C
280 K
D
290 K
Correct Answer
Option A
Detailed Explanation
The NCERT context indicates that n-butane has a boiling point of 273 K. Branched chain hydrocarbons typically have lower boiling points than their straight-chain isomers due to decreased surface area and weaker van der Waals forces.
