According to the reaction below and following the procedure outlined in this experiment, a student began with 0.700 g of aniline and 0.500 g of acetone. After reduction with sodium borohydride, the student recovered 0.650 g of the product, isopropyl aniline. Which is the limiting reactant? What was the theoretical yield of the product? What was the percent yield of the product? Write answers in the spaces provided and show all work in the space provided below or on the back of this sheet

Answer #1

A balanced chemical reaction is shown below.

The above equation shows that 1 equivalent of aniline reacts with 1 equivalent of acetone to form 1 equivalent of isopropyl aniline.

Limiting reagent is calculated by dividing number of moles and stoichiometric coefficient (SC). Mass is divided by molar mass to calculate number of moles.

As the number of moles of aniline is less, so it acts as limiting reagent in the reaction.
