Explain the difference between the boiling point of branched structure

1.	Explain the difference between the boiling point of branched structures of pentane (C_(5)H_(12)).
Answer» Solution :Alkane e.g. in the isomers of pentane `(C_(2)H_(12))` gas the BRANCH increases as the boiling point decreases. EXPLANATION : With increase in number of branched chains, the molecule attains the shape of a sphere. THis results in smaller area of contact and THEREFORE weak intermolecular forces betwen spherical moelcules there is decreases in boiling point.
