Question

Choose the incorrect  option from the following.

(a) Valence bond theory does not explain the paramagnetic nature of O2

(b) Molecular orbital theory explains the extra stability of O2^+  cation over O2

(c) Valence bond theory explains the ionization or gain of electrons, giving O2^+ and O2^–  ions, if O2  has the stable octet

(d) Resonance has no role in Molecular orbital theory

I had been asked this question in homework.

The question is from Homonuclear and Heteronuclear Molecules in portion Atoms to Molecules to Material’s for Engineers of Engineering Chemistry I

Answer 1

Right option is (c) Valence bond theory explains the ionization or gain of electrons, giving O2^+ and O2^–  ions, if O2  has the stable octet

Best explanation: Valence bond theory does not explain the ionization or gain of electrons, giving O2^+ and O2^–  ions, if O2 has the stable octet.
