75. Given below are two statements

Statement I : The boiling point of three isomeric pentanes follows the Order
n -pentane > isopentane > neopentane
Statement II : When branching increases, the molecule attains a shape of sphere. This results in smaller surface
area for contact, due to which the intermolecular forces between the spherical molecules are weak, thereby
lowering the boiling point.
