Question

the magnitude of london dispersion forces is proportional to which of the following?
number of single covalent bonds
ionic bonding
number of double covalent bonds
molecular mass of participating molecules

Explanation:

London dispersion forces are weak intermolecular forces arising from temporary dipoles. Their magnitude increases with the number of electrons (related to molecular mass) because more electrons lead to larger temporary dipoles and stronger interactions. The number of single/double covalent bonds or ionic bonding does not directly determine their strength.

Answer:

molecular mass of participating molecules
