,reduction, oxidation, or neither.

The oxidation numbers for each of the -CH₃ carbons in the compound ethane are equal to Term -1-2-3-40+1+2+3+4decreaseincreasean oxidationa reductionneither an oxidation or a reduction . If ethane is converted to ethene the oxidation numbers of the resulting =CH₂ carbons are now equal to Term 2-1-2-3-40+1+2+3+4decreaseincreasean oxidationa reductionneither an oxidation or a reduction . Because the values of the oxidation numbers are observed to -1-2-3-40+1+2+3+4decreaseincreasean oxidationa reductionneither an oxidation or a reduction , the conversion of ethane to ethene is considered to be Term 4-1-2-3-40+1+2+3+4decreaseincreasean oxidationa reductionneither an oxidation or a reduction .

If the compound ethene is hydrated to form ethanol, the oxidation number of the resulting -CH₃ carbon is equal to Term 5-1-2-3-40+1+2+3+4decreaseincreasean oxidationa reductionneither an oxidation or a reduction while the oxidation number of the -CH₂OH carbon is equal to Term 6-1-2-3-40+1+2+3+4decreaseincreasean oxidationa reductionneither an oxidation or a reduction . The change in oxidation number for the carbon that becomes -CH₃ is equal to Term 7-1-2-3-40+1+2+3+4decreaseincreasean oxidationa reductionneither an oxidation or a reduction and the change in oxidation number for the carbon that becomes -CH₂OH is equal to Term 8-1-2-3-40+1+2+3+4decreaseincreasean oxidationa reductionneither an oxidation or a reduction . Therefore, in the conversion of ethene to ethanol, the =CH₂ to -CH₃ conversion would be Term 9-1-2-3-40+1+2+3+4decreaseincreasean oxidationa reductionneither an oxidation or a reduction and the conversion of the =CH₂ to CH₂OH would be a/an Term 10-1-2-3-40+1+2+3+4decreaseincreasean oxidationa reductionneither an oxidation or a reduction . For the conversion, if the changes in oxidation number for each of the carbons are added together the resulting value of the change in the sum of the oxidation numbers is equal to Term 11-1-2-3-40+1+2+3+4decreaseincreasean oxidationa reductionneither an oxidation or a reduction . Therefore, in an overall sense, the conversion of ethene to ethanol is correctly considered to be Term 12-1-2-3-40+1+2+3+4decreaseincreasean oxidationa reductionneither an oxidation or a reduction ,
