What bond order does $O_2^{2 - }$ have
$3$
$2$
$1$
$0.5$
The bond order of a molecule is given by
Use molecular orbital theory to explain why the $\mathrm{Be}_{2}$ Molecule does not exist.
The species having bond order different from that in $\mathrm{CO}$ is
The hyperconjugative stabilities of tert-butyl cation and $2$-butene, respectively, are due to
The energy of $\sigma 2{{\rm{p}}_{\rm{z}}}$ molecular orbital is greater than $\pi 2{{\rm{p}}_{\rm{x}}}$ and $\pi 2{{\rm{p}}_{\rm{y}}}$ molecular orbitals in nitrogen molecule. Write the complete sequence of energy levels in the increasing order of energy in the molecule. Compare the relative stability and the magnetic behaviour of the following species : ${{\rm{N}}_2},{\rm{N}}_2^ + ,{\rm{N}}_2^ - ,{\rm{N}}_2^{2 + },$
