Question

Select the option containing every FALSE statement.

(i) Pairing two NO radicals can reduce the number of unpaired electrons.

(ii) The acid anhydride of HClO₄ is Cl₂O₅.

(iii) Hydrolysis of Ca₃N₂ can produce a basic gas and a basic hydroxide.

TestHub · Accepted Answer

Radical pairing can reduce spin, so (i) is true. The anhydride is Cl₂O₇, since Cl₂O₇+H₂O→2HClO₄; (ii) is false. Ca₃N₂+6H₂O→3Ca(OH)₂+2NH₃, so (iii) is true.
