Question

Why does butane have more boiling point than isobutane?​

Answer 1

butane have more boiling point than isobutane because :-

Butane has a straight chain structure whereas isobutane has a branched chain structure. A branched chain exhibits weaker Van Der Waals forces as compared to straight chains. Strong intermolecular forces in butane results in a higher boiling point as larger energy is required to separate them.

Answer 2

ANSWER:-------------

{ exhibits weaker Van Der Waals forces as compared to straight chains.}

{ Strong intermolecular forces in butane results in a higher boiling point as larger energy }
