In the synergic bond of metal carbonyls
${\pi ^*}$ molecular orbital of ligand is used
${\pi ^*}$ molecular orbital of metal is used
$\sigma $ molecular orbital of ligand as well as metals are used
${\sigma ^*}$ molecular orbital of metal is used
Two homo-diatomic molecules $'X'_2$ and $'Y'_2$ have same bond order then select the CORRECT statement
The species having no $P\pi - P\pi $ bond but has bond order equal to $O_2$
During the change of $O_2$ to $O_2^-$, the incoming electron goes to the orbital
The bond order of $NO$ molecule is
During the change of $O _{2}$ to $O _{2}^{-}$, the incoming electron goes to the orbital :
