Final answer:
The reaction of TsOH with H₂O typically leads to the formation of hydronium ions (H3O+). Without specific reactants, the exact major product cannot be determined. In reactions with alkenes, TsOH could result in alcohol formation.
Step-by-step explanation:
The student's question pertains to the outcome of a chemical reaction where TsOH (tosic acid) is mixed with H₂O (water). Typically, TsOH is a strong acid that will readily donate its proton (H+) to water, acting as a base in this scenario. The use of TsOH in water is commonly associated with reactions such as protonation or catalyzing hydration reactions. However, without additional information on the context or the reactants involved, it's challenging to predict a specific major product. If TsOH is used to protonate an alkene, for example, the major product would be the formation of a carbonation which could then react with water to form an alcohol. The general outcome is typically the transfer of the acidic proton to water forming hydronium ions (H3O+) and leaving the remaining part of the molecule (the tosylate anion).
