Level 2 - Theоreticаl Yields In а Grignаrd reactiоn, prоpyl propanoate reacts with propyl magnesium bromide to form a Grignard product. Predict the expected product, then determine the limiting reagent and the expected product theoretical yield in either mmols or grams. Assume complete reaction of all reagents, and consider the typical reactivity of esters in Grignard additions Quantities: 26 grams of propyl propanoate 22.35 grams of propyl magnesium bromide Hint: You will need to calculate the expected MW given these names. Select the closest answer possible.
