A potential energy diagram (distance between nuclei vs. potential energy, see Fi

Question

A potential energy diagram (distance between nuclei vs. potential energy, see Fig. 1.8 in your text) can be drawn to represent the potential energy when the 1s orbitals of two Hydrogen atoms overlap. The distance between the Hydrogen nuclei at which the potential energy is at a minimum is the: a. distance at which the anti-bonding molecular orbital is occupied. b. distance at which no attraction exists between the two atoms. c. distance at which the attraction between the two atoms is at a minimum. d. normal bond length for H_2.

Explanation / Answer

(1)

(d)

The point of minimum potential energy in the potential energy curve corresponds to the normal bond length or normal observed distance between the two H-atoms in the H2 molecule.
