The Bond Length in Cl2 is 1.99 A. Which of the following statements about the valence-bond description of the Cl—Cl bond in Cl2 is false?

a) The bond is formed from the overlap of a 3p orbital on one Cl atom with a 3s orbital on the other Cl atom.

b) The orbital overlap decreases as the Cl atoms are pulled apart.

c) At Cl—Cl distances less than 1.99A, the potential energy of the Cl2 molecule molecule increases because of the electrostatic repulsion between the two Cl atoms.

d) Each of the overlapping orbitals has one electron in it.

e) The potential energy of the Cl2 molecule is at a minmum at a Cl—Cl distance of 1.99A
