Delocalised molecular orbitals are found in
$H_2$
$HS^-$
$CH_4$
$CO_3^{-2}$
All other species have simple sigma bonds but due to presence of $pi$ bond, $CO _3^{-2}$ have delocalised orbitals
The bond order is maximum in
The number of species from the following which are paramagnetic and with bond order equal to one is___________
$\mathrm{H}_2, \mathrm{He}_2^{+}, \mathrm{O}_2^{+}, \mathrm{N}_2^{2-}, \mathrm{O}_2^{2-}, \mathrm{F}_2, \mathrm{Ne}_2^{+}, \mathrm{B}_2$
Give energy level diagram obtained by over lapping of $2{{\rm{p}}_{\rm{z}}}$ orbitals.And give a diagram of the orbits of that composition.
Bond order of $1.5$ is shown by-
Which of the following molecular orbitals has two nodal planes
