Although $CN^-$ ion and $N_2$ molecule are isoelectronic, yet $N_2$ molecule is chemically inert because of
presence of more number of electrons in bonding orbitals
lone bond energy
absence of bond polarity
uneven electron distribution
Bond order of $C_2$ vapour is :
Which one of the following species does not exist under normal conditions ?
Which of the following is paramagnetic as well as it has fractional bond order ?
વિધાન : Ozone is powerful oxidising agent in comparison to $O_2$.
કારણ : Ozone is diamagnetic but $O_2$ is paramagnetic.
Number of molecules/species from the following having one unparred electron $15$. . . . . . $\mathrm{O}_2, \mathrm{O}_2^{-1}, \mathrm{NO}, \mathrm{CN}^{-1}, \mathrm{O}_2^{2-}$
