Question

1. what determines the strength of london dispersion forces?

a. the atomic mass of the central atom
b. the number of protons in the nucleus
c. the size and shape of the molecule
d. the number of hydrogen bonds

Explanation:

London - dispersion forces are weak intermolecular forces. Larger molecules with more electrons and greater surface - area (size and shape) have stronger London - dispersion forces. Atomic mass of the central atom and number of protons in the nucleus are not direct determinants. Hydrogen bonds are a different type of intermolecular force and not related to the strength of London - dispersion forces.

Answer:

C. The size and shape of the molecule
