MCQ
Which of the following species can function both as oxidizing as well as reducing agent ?
  • A
    $Cl^-$
  • B
    $ClO_4^-$
  • ✓
    $ClO^-$
  • D
    $MnO_4^-$
✓

Answer

Correct option: C.
$ClO^-$
c
Species               $O.N.$

$Cl^-$                    $-1$

$ClO_4^-$               $+7$

$ClO^-$                 $+1$

$MnO_4^-$            $+7$

$NO_3^-$               $+5$

In $ClO^-$ chlorine is in $+1$ oxidation state which can be increased or decreased thus it acts as an oxidising or reducing agent. In other given species the underlined elements are either minimum or maximum oxidation state.

Given below are two statements: one is labelled as Assertion $(A)$ and the other is labelled as Reason $(R).$

Assertion $(A) :$ Metallic character decreases and non-metallic character increases on moving from left to right in a period.

Reason $(R)$ $:$ It is due to increase in ionisation enthalpy and decrease in electron gain enthalpy, when one moves from left to right in a period.

In the light of the above statements, choose the most appropriate answer from the options given below :
