MCQ
The oxide, which cannot act as a reducing agent, is
- A$N{O_2}$
- B$S{O_2}$
- ✓$C{O_2}$
- D$Cl{O_2}$
✓
Answer
Correct option: C.
$C{O_2}$
c
(c) Reduction is accompanied by an increase in oxidation number of the reducing agent. $C$ belong to $IVA$ so the max - $O.N.$ is $+4$. In $C{O_2}$ the oxidation number of $C$ is $+4$, which cannot be further increased. Hence, $C{O_2}$ can not act as reducing agent.
