alleryOxidation in modern terms is defined as:
ALoss of electrons by a species
BGain of electrons by a species
CLoss of hydrogen atoms only
DGain of oxygen atoms only
Answer & Solution
Correct answer: A. Loss of electrons by a species
1. Modern view: oxidation = loss of electrons; equivalent to an INCREASE in oxidation state.
2. Reduction = gain of electrons (decrease in oxidation state).
3. The old 'loss of H' / 'gain of O' definitions are special cases of the electron-transfer view.
