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
According to the molecular orbital theory, the bond order in ${C_2}$ molecule is
In the following the correct bond order sequence is :
The total number of molecular orbitals formed from $2 \mathrm{~s}$ and $2 \mathrm{p}$ atomic orbitals of a diatomic molecule
The correct order of the $O-O$ bond length in $O_2$ , $H_2O_2$ and $O_3$ is
"Isoelectronic molecules and ions have identical bond orders." Explain by examples.
