option A) C₆H₁₂O₆ is oxidized and O₂ is reduced

Explanation:

1) Chemical equation:

C₆H₁₂O₆ + 6O₂ → 6CO₂+ 6H₂O + Energy

2) Oxidation states in the reactants

a) C₆H₁₂O₆

The oxidation state of all H atoms is +1.The oxidation state of all O atoms is -2

Here, you will see that the oxidation state of carbon in glucose is zero.

There are 6 atoms of C which may have different oxidation number.

You can work with a more developed formula such as:

O OH OH OH OH OH

║ | | | | |

H - C¹ - C² - C³ - C⁴ - C⁵ - C⁶ - H

| | | | |

H H H H H

C¹ is bonded to one O, one C and one H.

∴ C¹ 's oxidation state may be determined from x + (−2) + (0) + (+1) = 0

⇒ x = + 1

C²,C³,C⁴, and C⁵ are bonded to one OH radical, two C atoms, and one H atoms.

∴ Their oxidation states are given by:

x + (−1) + 2(0) + (+1) = 0 ⇒ x=0

C⁶ is bonded to one OH, one C, and two H atoms.

∴ C⁶ 's oxidation state may be determined from:

x + (−1) + (0) + 2(+1) = +1 ⇒ x = −1

The overall oxidation state of C in that molecules is the algebraic sum of all each of C atom oxidation states: +1 + 0 + 0 + 0 + 0 + (-1) = 0

b) O₂ : since it is alone, its oxidation state is zero.

3) Oxidation states in the products

c) CO₂

Oxidation state of O: -2Oxidation state of C: +4

d) H₂O

Oxidation state of O: -2Oxidation state of H: + 1

4) Changes in the oxidation state

C changed from 0 in the reactats to +4 in the productsO changed from O in the reactants to - 2 in the products

5) Conclusion:

Since C increased its oxidation state, it is oxidizedSince O reduced its oxidation state, it is reduced. option A) C₆H₁₂O₆ is oxidized and O₂ is reduced
