Question

What property of low-molecular weight aldehydes and ketones accounts for the magnitude of their boiling points?
Options
A The ability to form strong H-bonds between their molecules.
B The ability of the carbonyl oxygen to form H-bonds with other carbonyl groups.
C The ability of the polar carbonyl group to attract other polar molecules.
Correct Answer
D The ability of the carbonyl group to attract electrophiles and form bonds.
Correct Answer

Option C is the correct answer.

Detailed Explanation

Aldehydes and ketones have higher boiling points than alkanes of similar size due to dipole-dipole interactions from the polar carbonyl group. They cannot form strong hydrogen bonds with each other (no O-H group).

Hint

What intermolecular forces are present in carbonyl compounds?
