Question

Which of the following compounds have the same oxidation level, and which have different levels?

Short answer

Same oxidation level

Different oxidation level

Step-by-step solution

Oxidation level (OL)

For organic compounds, the oxidation level of the carbon is calculated by counting the number of bonds bonded to more electronegative atoms other than carbon.

Compound with the same oxidation level

Epoxides have single oxygen so their OL is 1, for alcohol as there is one OH group the OL is 1 whereas in the case of ketone there is a double bond between carbon and oxygen. So, its OL is 2 and for alkene, there is a double bond its OL is -2

Thus, compounds 1,2, and 4 have the same OL and 3 and 5 have different oxidation levels.

Thus, the compounds with the some OL are:

Same oxidation level

Compounds with different oxidation level:

Different oxidation level
