Answer :
Final answer:
The reaction mechanism for the synthesis of triphenyl methanol from the reaction of Methyl benzoate and a Grignard Reagent involves the formation of a Grignard Reagent, nucleophilic addition, protonation, and elimination reactions. The Grignard Reagent acts as a nucleophile and attacks the carbonyl carbon of Methyl benzoate, forming an intermediate. The intermediate is then protonated and undergoes elimination to yield triphenyl methanol.
Explanation:
The synthesis of triphenyl methanol from the reaction of Methyl benzoate and a Grignard Reagent involves several steps:
- Formation of the Grignard Reagent: The Grignard Reagent is formed by reacting magnesium metal with an alkyl or aryl halide. In this case, the Grignard Reagent is formed by reacting an appropriate alkyl or aryl halide with magnesium metal.
- Nucleophilic Addition: The Grignard Reagent acts as a nucleophile and attacks the carbonyl carbon of Methyl benzoate, forming an intermediate. The oxygen of the carbonyl group becomes negatively charged.
- Protonation: The negatively charged oxygen of the intermediate is protonated by an acid, such as water or an alcohol. This protonation step generates a hydroxyl group.
- Elimination: The hydroxyl group is eliminated, resulting in the formation of triphenyl methanol.
Overall, the reaction mechanism for the synthesis of triphenyl methanol involves the formation of a Grignard Reagent, nucleophilic addition, protonation, and elimination reactions.
