Reduction potentials of A,B,C and D are 0.8 V 0.79 V, 0.34 V and -2.37 V respectively which element displaces all the other three elements

A

B

B

A

C

D

D

C

Text Solution

Verified by Experts

The correct Answer is:
C
The element having lower reduction potential canf displace metal having higher reductional potenital
`because` R eduction potential of D is least among given elemnets
`therefore` it can displace all other metals
