Isobutane

Vedclass · Answer

(A) The boiling point of alkanes depends on the surface area and branching. $n$-Butane is a straight-chain alkane with a higher boiling point than its branched isomer,isobutane. Isobutane ($2$-methylpropane) has more branching,which reduces the surface area and thus the van der Waals forces,resulting in a lower boiling point compared to $n$-butane. Among the given options,isobutane has the lowest boiling point due to its compact branched structure.

Which of the following has the minimum boiling point?
