Which one of the following will have the higher boiling point: acetone or 2- methylpropane? explain why. (blb ch. 11)

Acetone has higher boiling point.

Explanation:

Acetone is polar molecule due to presence of polar carbonyl group. Hence dipole exists in acetone molecule. Therefore, as a result, dipole-dipole attraction force exists between acetone molecules along with inherent london-dipole force.2-methylpropane is a non-polar saturated alkane. Hence only london dispersion force exists between 2-methylpropane molecules.Therefore intermolecular force is stronger in acetone than 2-methylpropane. Hence higher temperature is required to remove this intermolecular force and boil liquid acetone molecule as compared to 2-methylpropane.So, acetone has higher boiling point.

The answer for this question is d. none of these

Noble gases is far right
