  1. m-bromobenzenesulfonic acid
  2. 3-nitro-4-bromobenzoic acid

Solution

  1. Solved Problem
  2. Solved Problem
  3. Nitration of p-BrC6H4CH3 would have given about a 50-50 mixture of two products; 2-nitro-4-bromotoluene would be unwanted. When oxidation precedes nitration, an excellent yield of the desired product is obtained.
