Which statement describes the difference between covalent bonds and Van der Waals forces?
A. Covalent bonds form when there is an attraction between
nonpolar molecules, while Van der Waals forces cause two atoms
to share valence electrons.
B. Covalent bonds occur when two atoms share valence electrons,
while Van der Waals forces cause an attraction between positive
and negative ions.
C. Covalent bonds form when two atoms share valence electrons,
while Van der Waals forces cause an attraction between nonpolar
molecules
D. Covalent bonds form from the attraction of positive ions and freely
moving electrons, while Van der Waals forces cause an attraction
between nonpolar molecules.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
