Carboxylic acids can be made by the hydrolysis of nitriles, which in turn can be made from an alkyl halide. Draw the structures of a starting alkyl bromide and the intermediate nitrile that would be used in the synthesis of phenylacetic acid. Do not show free ions.
alkyl bromide ? ----NaCN---> Nitrile ? ---6M HCI H2O HEat-----> forms phenylacetic acid
