Question

Which of the following factors influences the magnitude of vander waal forces:

• A. Molecular Size
• B. Source of isolation of compound
• C. Both A and B
• D. None of the above

Answer 1

Answer: (A)

Molecular Size

Molecular Size (Molar mass). Larger the molecular size or its complexity greater is the probability of polarisation or distortion and higher is the magnitude of van der Waals forces.So the Molecular Size influences the magnitude of vander waal forces.
Hence option A is correct.
