Vedclass · Answer

(B) London dispersion forces are directly proportional to the surface area of the molecule. For isomers,the strength of London forces decreases with an increase in branching because the molecule becomes more spherical,reducing the surface area available for intermolecular contact. $n$-pentane is a straight-chain isomer with the largest surface area among the given pentane isomers,leading to the strongest London forces. $neo$-pentane is the most branched and has the smallest surface area,resulting in the weakest London forces.
