Final answer:
During this reaction, bond breaking and bond formation as well as proton transfer occur at the molecular level.
Step-by-step explanation:
During a chemical reaction, various atomic rearrangements can occur at the molecular level. In the given options, the atomic rearrangements that take place are:
- Bond breaking and bond formation: This involves the breaking of existing chemical bonds and the formation of new chemical bonds.
- Proton transfer: In certain reactions, protons can be transferred between molecules, resulting in the formation of different products.
These atomic rearrangements occur as a result of the interactions between the reactant molecules and the energy changes associated with the specific reaction.
