Among the following, the molecule expected to be stabilized by anion formation is :

C_{2},O_{2},NO,F_{2}

  • Option 1)

     C_{2}   

  • Option 2)

    F_{2}

  • Option 3)

    NO

  • Option 4)

    O_{2}

Answers (1)

C_{2}^{-},F_{2}^{-},O_{2}^{-},NO^{-}

we know , stability of molecules \propto Bond order .

In C_{2}^{-} , the e^{-} enters in 6\; 2\rho z orbital

So the bond order =\frac{N_{b}-N_{a}}{2} will increase by 0.5

So, the stability would increase.


Option 1)

 C_{2}   

Option 2)

F_{2}

Option 3)

NO

Option 4)

O_{2}
