Which of the following is NOT considered an example of oxidation?

Which of the following is NOT considered an example of oxidation?

Options

  1. AFormation of magnesium oxide (MgO)
  2. BConversion of sulfur (S) to sulfur dioxide (SO2)
  3. CCombustion of methane (CH4) to carbon dioxide (CO2) and water (H2O)
  4. DReduction of mercury oxide (HgO) to mercury (Hg) and oxygen (O2)

Correct answer

D. Reduction of mercury oxide (HgO) to mercury (Hg) and oxygen (O2)

Step-by-step solution

The passage states that reduction is the removal of oxygen or electronegative elements, so the reduction of mercury oxide does not fall under the definition of oxidation.
