When synthesize Vanillin from 4-hydroxybenzaldehyde, the first step is bromination. a. Explain why bromine is added at the ortho position relative to the hydroxy (-OH) group, by proposing a plausible mechanism. b. Draw all important resonance contributors involved in the reaction mechanism. c. When excess of bromine is used, a di-bromo derivative (containing 2 Br groups) is formed. Draw the structure of this product.
