9.42. Hydrogen peroxide in the name of perhydrolis used as

(a) Antipyretic

(b) Antiseptic

(c) Analgesic

(d) All of the above

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

Compound             Melting Point (K)

HF                          190
