9.45. Choose the incorrect statement.

(a) H₂O₂has planar structure.

(b) Alkali oxides present in glass catalyse the decomposition of H₂O₂.

(c) Decomposition of H₂O₂ is a disproportionation reaction.

(d) H₂O₂ molecule simultaneously undergoes oxidation and reduction.

H₂S has minimum boiling point.

PbS + 4H₂O_2->PbSO₄ + 4H₂O.

Volume strength of H₂O₂ = Molarity * 11.2

HF molecules are associated with strong intermolecular hydrogen bonding hence its boiling point is the highest
