Chapter 21, Problem 32P
A compound X (C10H14O) dissolves in aqueous sodium hydroxide but is insoluble in aqueous sodium bicarbonate. Compound X reacts with bromine in water to yield a dibromo derivative, C10H12Br2O. The 3000–4000-cm−1 region of the IR spectrum of X shows a broad peak centered at 3250 cm−1; the 680–840-cm−1 region shows a strong peak at 830-cm−1. The 1H NMR spectrum of X gives the following: singlet at δ 1.3 (9H), singlet at δ 4.9 (1H), and multiplet at δ 7.0 (4H). What is the structure of X?
