Which of the following is not an example of redox reaction?
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
As oxidation number of Cu is changed from +2 to O and that of H is changed from 0 to +1 , this is an example of redox reaction.
As oxidation number of Fe changes from +3 to O and that of C changes from +2 to +4 , this is an example of redox reaction.
As oxidation number of K changes from O to +1 and that of F changes from O to -1 , this is an example of redox reaction.
Oxidation number of all the elements remains unchanged. Hence, this is not an example of redox reaction.
