Question

What is the major product obtained when two moles of ethyl magnesium bromide is treated with methyl benzoate followed by acid hydrolysis?

Answer 1

Ans:the answer for your question is in the pic

Explanation:

Answer 2

Triphenyl methanol is the product.

Explanation:

• The reactant is methyl benzoate.

• The reagent is phenyl magnesium bromide in ether solution.

• So, here the grignard acts as a strong nucleophile.

• This attacks the carbonyl carbon, producing a tetrahedral intermediate as shown in the diagram.

• Then with the elemination of methanol from the molecule, it becomes benzophenone.

• This benzophenone is again attacked by the grignard, producing triphenyl methyl alkoxide and magnesium bromide.

• This is then hydrolysed to form triphenyl methyl alcohol and basic magnesium bromide.
