Question

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

Answer 1

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).
