Explain formation of $\mathrm{H}_{2}$ and energy level diagram of $\mathrm{H}_{2}$ molecule.
Which of the following pairs have identical values of bond order ?
Which of the following has unpaired electron $(s)$ ?
According to Molecular Orbital Theory,
($A$) $\mathrm{C}_2^{2-}$ is expected to be diamagnetic
($B$) $\mathrm{O}_2{ }^{2+}$ is expected to have a longer bond length than $\mathrm{O}_2$
($C$) $\mathrm{N}_2^{+}$and $\mathrm{N}_2^{-}$have the same bond order
($D$) $\mathrm{He}_2^{+}$has the same energy as two isolated He atoms
Which of the following best describes the diagram of molecular orbital?
