23. When comparing Be2 and H2:I. Be2 is more stable because it contains both bonding andantibonding valence electrons.II. H2 has a higher bond order than Be2.III. H2 is more stable because it only contains 1s electrons.IV.H2 is more stable because it is diamagnetic, whereas Be2 isparamagnetic.(A) I, II (B) III only (C) II, III (D) II, III, IV (E) III, IV
