Question

Consider the given set of species and select correct statements.

H₂ , Li₂ , B₂ , C₂ , N₂ , O₂ , F₂

Condition 1 $\Rightarrow$ Diamagnetic molecule

Condition 2 $\Rightarrow$ Last e⁻ present in gerade B.M.O.

Condition 3 $\Rightarrow$ On e⁻ addition, stability decreases.

TestHub · Accepted Answer

Condition 1 (Diamagnetic): H₂ (all electrons paired).

Condition 2 (Last $e^{-}$ in gerade B.M.O.): H₂ ( $σ_{1 s}$ ), Li₂ ( $σ_{2 s}$ ), and N₂ ( $σ_{2 p z}$ ).

Condition 3 (Stability decreases on $e^{-}$ addition): H₂, Li₂, N₂, O₂, F₂ (where the added electron enters an antibonding orbital, decreasing the bond order).

Summary of Species:

All 3 conditions: H₂, Li₂, N₂ (3 species)

Only 2 conditions: F₂ (follows C1 and C3)

Only 1 condition: C₂ (follows C1) and O₂ (follows C3)

0 conditions: B₂ (1 species)

Statements (C) and (D) are the correct options.
