It is essential to acknowledge that the depicted reaction is not viable due to the insufficient reactivity of molecular hydrogen (H 2 ) for the reduction of acetic acid. Typically, this reaction necessitates a suitable reducing agent, such as lithium aluminum hydride (LiAlH 4 ). However, identifying and substituting the appropriate reducing agents can be problematic. Some chemists use a convention to simplify chemical notations where the reducing agent is represented as [H] without specifying the exact compound. Following this convention, we have updated the notation from molecular hydrogen (H 2 ) to two single hydrogen atoms (H). This new representation indicates the presence of a reducing agent distinct from elemental hydrogen. Likewise, the depiction of molecular oxygen as O 2 has been revised to two single oxygen atoms (O), symbolizing its role as an oxidizing agent.
