Question
Which of the following best explains why the melting points of saturated fats increase with increasing molecular weight?
Correct Answer
Option D is the correct answer.
Detailed Explanation
Melting points increase with increasing molecular weight because larger molecules have stronger intermolecular van der Waals forces (London dispersion forces) due to increased surface area and polarizability.
Hint
How do intermolecular forces change with molecular weight?
