NEETChemistryRedox Reactions
Which of the following is NOT considered an example of oxidation?
Options
- AFormation of magnesium oxide (MgO)
- BConversion of sulfur (S) to sulfur dioxide (SO 2 )
- CCombustion of methane (CH 4 ) to carbon dioxide (CO 2 ) and water (H 2 O)
- DReduction of mercury oxide (HgO) to mercury (Hg) and oxygen (O 2 )
Correct answer
D. Reduction of mercury oxide (HgO) to mercury (Hg) and oxygen (O 2 )
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.
