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.

Answer:

a. energy is absorbed in the reaction.

explanation:

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
