Answer:
Step-by-step explanation:
Esters (methyl benzoate) react with Grignard reagents to form ketones. Ketones which are more reactive than esters then react with Grignard reagents to form the tertiary alcohol triphenylmethanol. Therefore, we can say Esters reacts with two identicals of Grignard reagents. The reaction proceeds so that methyl benzoate reacts with excess phenylmagnesium bromide, followed by the protonation of H3O+ to form triphenylmethanol.
