The oxidation state of carbon-atom in glucose is:
Correct answer: D. Zero
- A. +4
- B. -4
- C. +6
- D. Zero
Explanation
Net charge on carbon in glucose is zero.C6H12O66x+12+(-2)6=0Let x be net oxidation state of carbon.6x=0x=0Option D accurately represents the oxidation state of carbon in glucose. The calculation based on the molecular formula C6H12O6, considering hydrogen's oxidation state of +1 and oxygen's oxidation state of -2, shows that the net oxidation state of carbon is indeed 0. This means that the carbon atoms in glucose are neither oxidized nor reduced when considering the distribution of electrons in covalent bonds.

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.
