2 H?O? → 2 H?O + O?

(b) Compounds like KClO?, Pb(NO?)?, and NaNO? liberate dioxygen on heating.
— Correct. These compounds release oxygen gas upon thermal decomposition.

(c) 2-Ethylanthraquinol is useful for the industrial preparation of hydrogen peroxide.
— Correct. It is used in the anthraquinone process, which is a commercial method for producing H?O?.

(d) Hydrogen peroxide is used in the manufacture of sodium perborate.
— Correct. H?O? reacts with borax and sodium hydroxide to produce sodium perborate.

Correct Option: 1 — a, b, c and d
