"ucture and properties of Matter Question 1 of 20

Which statement describes the difference between covalent bonds and Van

der Waals forces?

O A. Covalent bonds form from the attraction of positive ions and

freely moving electrons, while Van der Waals forces cause an

attraction between nonpolar molecules.

B. Covalent bonds form when there is an attraction between

nonpolar molecules, while Van der Waals forces cause two atoms

to share valence electrons.

C. Covalent bonds occur when two atoms share valence electrons,

while Van der Waals forces cause an attraction between positive

Covalent bonds form when two atoms share valence electrons,

while Van der Waals forces cause an attraction between nonpolar

molecules

Explanation:

A covalent bond is said to be formed when two atoms of the same or different elements share electrons. In an ordinary covalent bond, each bonding atom contributes one valence electron while in a dative covalent bond only one of the bonding atoms provides the shared pair of electrons.

Van Der Waals forces is the major intermolecular interaction between non polar compounds. Van Der Waals forces " are caused by correlations in the fluctuating polarizations of nearby particles"(Wikipedia).

when a reversible reaction is occurring in both directions at the same rate; the products and reactants do not change in concentration. a chemical reaction where the compound is broken into its constituent parts.
