"Isoelectronic molecules and ions have identical bond orders." Explain by examples.
Which of the following diatomic molecular species has only $\pi$ bonds according to Molecular Orbital Theory?
The correct order of the $O-O$ bond length in $O_2$ , $H_2O_2$ and $O_3$ is
The species having bond order different from that in $CO$ is
Oxygen molecule is paramagnetic because
