Which of following has "higher boiling"and "melting point"?

Explanation

OPTION A: Acetone has a boiling point of 56.5°C and a melting point of -94.9°C. It is a relatively small molecule and lacks the ability to form hydrogen bonds, resulting in weaker intermolecular forces.OPTION B: 2-butanol has a higher molecular size and the presence of an -OH group, allowing for intermolecular hydrogen bonding. Hydrogen bonding leads to stronger intermolecular forces, resulting in higher boiling and melting points. 2-butanol has a boiling point of 99.5°C and a melting point of -114.5°C.Hence, B is the correct option.OPTION C: Propane (C3H8) is a small molecule with weak London dispersion forces between its nonpolar molecules. It has a boiling point of -42.1°C and a melting point of -187.7°C.OPTION D: 2-methyl propene (also known as isobutylene) (C4H8) is also a small molecule with weak intermolecular forces. It has a boiling point of -6.9°C and a melting point of -159.7°C.
