Which list places the molecules, from left to right, from most oxidized to least oxidized?

Question

Quizplus · Accepted Answer

To determine the oxidized state of a molecule, you need to look at the oxidation number of each of its atoms. The general rule is that more electronegative atoms have a higher oxidation state, while less electronegative atoms have a lower oxidation state. In option C, COS has the highest oxidation state (+4 for C, and -2 for O and S), followed by CHOOH (+2 for C in COOH, and -2 for O), then CH₃OH (+2 for C in CH, +3 for S, -1 for O and H), and finally, CH₄ (+2 for C in CH, and -1 for each H atom). Therefore, the correct order from most oxidized to least oxidized is: CO₂ > CHOOH > CH₃OH > CH₄.
