Question

Three elements $A, B$ and $C$ having reduction potential $-1.5,-0.5$ and $1.5\,V$ respectively then arrange them in correct order according to reducing power:

• A. A>B>C
• B. B>A>C
• C. C>B>A
• D. B>C>A

Answer 1

Answer: (A)

A>B>C

Answer 2

Key Greater the reduction potential, less is reducing power.
Given reduction potential of $A=-1.5 \,V$
reduction potential of $B=-0.5 \,V$
reduction potential of $C=+1.5 \,V$
$\therefore$ The correct order of reducing power is
$A > B > C$
