What happens during an oxidation reaction in organic chemistry?

• A. The compound decreases in oxidation state
• B. The compound increases in oxidation state, often involving loss of electrons
• C. The compound undergoes hydrolysis
• D. The compound forms a new carbon-carbon bond

Answer: (B)

During an oxidation reaction in organic chemistry, the key change that occurs is an increase in the oxidation state of the compound. This process is often associated with the loss of electrons, which can occur through various mechanisms, such as the removal of hydrogen atoms or the addition of oxygen atoms. Oxidation signifies a transformation where an organic molecule loses electrons, resulting in a higher oxidation state. For example, when an alcohol oxidizes to form a ketone or aldehyde, the alcohol (which has a specific oxidation state for carbon) transitions to a higher oxidation state in the carbonyl compound. This increase in oxidation state correlates directly with the concept of electron loss, as the electron density around the carbon is decreased when it forms a bond to a more electronegative atom, such as oxygen. In contrast, the other options present different chemical processes. A decrease in oxidation state would suggest a reduction reaction, where electrons are gained instead. Hydrolysis involves the reaction with water and the breaking down of compounds, unrelated to changes in oxidation states. Forming a new carbon-carbon bond describes different types of reactions, such as coupling, rather than oxidation. Thus, the foundational aspect of oxidation being an increase in oxidation state, often through electron loss, is why
