Statement I : | The boiling point of three isomeric pentanes follows the order \(\text { n-Pentane }>\text { Isopentane }>\text { Neopentane }\) |
Statement II : | When branching increases, the molecule attains the 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. |
