Question

According to molecular orbital theory, what is the bond order in the Cl2+ ion?

A) 2.0
B) 1.5
C) 0.5
D) 1.0
E) 3.0
                            

Select the statements regarding MO theory that are true.

A) An increase in bond order results in longer, stronger bonds
B) The linear combination of three atomic orbitals gives rise to a bonding, a nonbonding, and an antibonding combination.
C) Population of antibonding orbitals results in a weaker, shorter bond.
D) The stretching frequency increases with an increase in bond length.
E) Nonbonding orbitals can be delocalized.

From the statements below, choose all that are true.

A) The correct ordering of bond strengths is δ > π > σ.
B) σ antibonds have one nodal surface that contains the nuclei of the bonded atoms.
C) A σ bond can be formed using a d and a p orbital.
D) δ bonds have two nodal surfaces that contain the nuclei of the bonded atoms.
