Chemistry - CHEMICAL BONDING Question with Solution | TestHub

(A) Correct: Due to s–p mixing in N₂, σ2p becomes more stable and σ*2p increases in energy.

(B) Correct: An MO symmetrical about the internuclear/bond axis is designated as σ MO; if antibonding, it is σ*.

(C) Incorrect: O₂ has higher bond energy but shorter bond length than C₂, so both cannot be higher.

(D) Correct: B₂ has 2 unpaired electrons, while O₂ also has 2 unpaired electrons.

Hence, correct statements are A, B and D.
