Which of the following Van der waals forces would have the most action among molecules of methane (CH4) ?

A) Dipole-dipole

B) ion-dipole

C) london dispersion

2. What type of bond is formed when when electrons are transferred from a cation to an anion?

A) ionic bond

B) covalent bond

C) Metallic bond

1) Answer is: C) London dispersion.

The London dispersion force is the weakest and temporary attractive intermolecular force. Atoms of one molecule induce temporary dipole at another molecule.

2) Answer is: A) ionic bond.

Ionic bond is formed by the attraction of oppositely charged atoms (cations andanions).
