Among the following, the molecule expected to be stabilized by anion formation is : `C_(2), O_(2), NO, F_(2)`

A

`C_2`

B

`O_2`

C

NO

D

`F_2`

Text Solution

Verified by Experts

The correct Answer is:
A
`C_2^(-):(sigma1s)^(2)(sigma^(**)1s)^(2)(sigma2s)^(2)(sigma^(**)2s)^(2)(pi2p_x^2=pi2p_y^2)`
or `KK(sigma2s)^(2)(sigma^(**)2s)^(2)(pi2p_x^(2)=pi2p_y^(2))pi2p_z^(1)`
Bond order: `1/2(9-4)=2.5`
