Which of these statements correctly describes the electronic charge distribution

Question

Which of these statements correctly describes the electronic charge distribution in a molecule? I. The charge density around each atom is the same as it is in the free atom. II. The electronic charge is distributed equally around each atom in the molecule. III. Electrons are attracted preferentially to atoms with high electronegativity. IV. Electronic charge density is enhanced in the space between atoms to form a bond. V. Electrons are always shared between atoms and never transferred from one atom to another. a. I only b. II and III only c. III and IV only d. II only e. V only

Explanation / Answer

(c) III and IV are correct.

* Electrons are attracted preferentially to atoms with with high electronegativity.

* Electonic charge density is enhanced in the space between atoms to form a bond.
