The oxidation number of oxygen atom in OF2 and H2O2:
Correct answer: B. +2, -1
- A. -2, -1
- B. +2, -1
- C. -1, +2
- D. +2, +1
Explanation
Option B is correct.The oxidation number of oxygen atom in OF2 and H2O2 are different.In OF2, the oxidation number of oxygen is +2. This is because oxygen is more electronegative than fluorine, so it has a greater tendency to attract electrons. If all of the bonding electrons in the OF2 molecule were assigned to oxygen, then oxygen would have a charge of +2.OF2O+2(-1)=0O-2=0O= +2 In H2O2, the oxidation number of oxygen is -1. This is because hydrogen is less electronegative than oxygen, so it has a greater tendency to lose electrons. If all of the bonding electrons in the H2O2 molecule were assigned to oxygen, then oxygen would have a charge of -1. H2O2 2 (+1) + 2O = 02O = -2O = -1

About Electrochemistry
Electrochemistry describes electron transfer through oxidation and reduction, identifies oxidizing and reducing agents, and applies oxidation numbers to balance redox equations. It also covers electrode potential and the standard hydrogen electrode, which provides the reference for comparing the reduction tendencies of other electrodes.
