Question

A procedure calls for the bromination of 12 mmol of trans‑cinnamic acid with 12 mmol of Br 2 in glacial acetic acid solvent. Select the likely consequence of accidentally using 6 mmol of Br 2 instead. The yield of dibromide product will be approximately one‑half of the expected yield. The yield of dibromide will not change because 2 mol of Br 2 react with 1 mol of trans‑cinnamic acid. The yield will not change because acetic acid is the limiting reactant. The yield of dibromide product will not change, as the equilibrium strongly favors the product.

Answer 1

Answer: The yield of dibromide product will be approximately one‑half of the expected yield.
