हिन्दीGiven 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. In the light of the above statements, choose the most appropriate answer from the options given below:
Correct answer · Option 3
Both Statement I and Statement II are correct.
Explanation
Both statements are correct. Branching decreases surface area, making molecules more spherical and weakening van der Waals interactions, which lowers the boiling point.
