Practice objective / multiple choice question 1 from the 2023 Waec Model Questions Vol1 Chemistry examination.
10.0 g of styrene (C₈H₈) is brominated in aqueous solution to give 1‑bromo‑2‑phenylethanol as the major product. The bromohydrin is then dehydrated with concentrated H₂SO₄ to afford trans‑1‑bromo‑1‑phenylethene (C₈H₇Br). If the overall isolated yield of the final alkene is 65 % based on the initial styrene, calculate the mass of trans‑1‑bromo‑1‑phenylethene obtained.
