What is meant by the term bond order? Calculate the bond order of : N2, O2, O2⁺ and O2⁻.
In molecular orbital theory, the bond order of a diatomic molecule is calculated as:
Which of the following diatomic molecules is paramagnetic according to molecular orbital theory?
Draw molecular orbital diagram for N2+ molecule.
N2 is diamagnetic while O2 is paramagnetic. Explain on the basis of Molecular orbital theory.
Arrange the following in the order of property indicated for each set: (i) O2, O2+, O2–, O22– (increasing stability) (ii) LiCl, NaCl, KCl, RbCl (decreasing covalent character) (iii) NO2, NO2+, NO2– (decreasing bond angle) (iv) H–F, H–Cl, H–Br, H–I (decreasing bond dissociation enthalpy)
