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.
