Among the following, the molecule expected to be stabilized by anion formation is: $${C}_{2},{O}_{2},NO,{F}_{2}$$

A$$NO$$
B$${C}_{2}$$
Correct Answer
C$${F}_{@}$$
DO2

Solution

In case of only $$C_2$$ incoming electron will enter in the bonding molecular orbital which increases the bond order and stability too. Whereas rest of all takes electron in their antibonding molecular orbital which decreases bond order and stability
