Question

Which one of the following has the minimum boiling point? (A) n-Butane (B) Isobutane (C) 1-Butene (D) 1-Butyne
​brief reason plz...

Answer 1

The answer is B.ISOBUTANE

Among isomeric alkanes, the straight chain isomer ha higher boiling point than the branched chain isomer. The greater the branching of the chain, the lower is the boiling point. Further due to the presence of π electrons, these molecules are slightly polar and hence have higher boiling points than the corresponding alkanes
