Which of the following would have same magnetic nature whether $sp$ mixing is operative or not?
$C_2$
$B_2$
$O_2$
All of these
Which of the following molecule is paramagnetic
The bond order in $O_2^ + $ is
During change of $O^2$ to $O_2^-$ ion, the electron adds on which one of the following orbitals?
Explain in Short : $\mathrm{MO}$ occupancy and molecular properties for ${{\rm{B}}_2}{\rm{,}}{{\rm{C}}_2}{\rm{, }}{{\rm{N}}_2},{{\rm{O}}_2}{\rm{,}}{{\rm{F}}_2},{\rm{N}}{{\rm{e}}_2}$.
A simplified application of $MO$ theory to the hypothitical molecule $'OF'$ would give its bond order as :-
