In which pair, the stronger bond is found in the first species?a) O2- ,O2 b) N2 ,N2- c) NO+ ,NO-

B) →N214, N2+13     Number of bonding electrons decreases,hence bond order decreases,hence bond strength decreases.C)→ NO+14, NO-16Number of antibonding electrons increases,hence bond order decreases,hence bond strength decreases. B.O ∝ Bond strengthA) → O2-17, O216Number of antibonding electrons decreases,hence bond order increases and hence bond strength increases
