Bonding in Some Homonuclear Diatomic Molecules

Explain the magnetic nature of oxygen molecule.

How do you explain the paramagnetic property of ${\mathrm{O}}_2$ molecule using the molecular orbital configuration of ${\mathrm{O}}_2$ .

Calculate the bond order and predict the magnetic property of ${\mathrm{Li}}_2$ molecule.

What is the effect of the following ionisation process on the bond order in ${\mathrm{C}}_2$?

${\mathrm{C}}_2\stackrel{ }{\to }{{\mathrm{C}}_2}^{+}+{\mathrm{e}}^{-}$

O₂ is a paramagnetic molecule

The correct statement with regard to ${{\mathrm{H}}_2}^{+} \mathrm{and} {{\mathrm{H}}_2}^{-}$ is:

In ${\mathrm{He}}_2,$ then electrons in bonding and anti-bonding orbitals are

The excited electronic state of ${\mathrm{H}\mathrm{e}}_2$ does not have

Which of the following MO is the lowest energy MO for B₂ molecule?

Among $\mathrm{N}{\mathrm{O}}_2^{+}\mathrm{ },\mathrm{ }{\mathrm{K}\mathrm{O}}_2$ and ${\mathrm{N}\mathrm{a}}_2{\mathrm{O}}_2$ and ${\mathrm{N}\mathrm{a}\mathrm{A}\mathrm{l}\mathrm{O}}_2$ , the paramagnetism exist in:

The production of band spectra is caused by

In forming (i) ${\mathrm{N}}_2⟶{\mathrm{N}}_2^{+}$ and (ii) ${\mathrm{O}}_2⟶{\mathrm{O}}_2^{+}$; the electrons respectively are removed from

$\mathrm{R}\mathrm{b}{\mathrm{O}}_2$ is
