Esterification of benzyl acetate - Limiting Reagent and Reaction Help
In my lab, we synthesized benzyl acetate from sodium acetate and benzyl bromide. We used 1.5 g of sodium acetate and 0.9 equivalents of benzyl bromide (2.81 g which was in liquid form so 1.95 mL) with 10 mL of DMF solvent (+ water to quench). I need help with what the reaction is and then what the limiting reagent would be. Thanks!

what is my limiting reagent, theoretical yield
calculated from moles , and % yield for the synthesis of banana
oil?
Isoamyl acetate (banana oil) is made by the acid
catalyzed reaction (fischer esterification) between isoamyl alcohol
and acetic acid. sulfuric acid was used as the catalyst for the
fast conversion of product from starting alcohol and acid. the
catalyst only affects the rate of the reaction not the extent of
the reaction.

Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol.
