Correct answer: 1

It is given in the question that, compound A gives a characteristic colour with neutral FeCl ₃ solution and soluble in NaOH solution that means it contains a phenolic group. Since compound ' A ' when treated with Br ₂ forms compound ' B ' with molecular formula C ₇ H ₅ OBr ₃ (ppt.). Considering the given information the given compound is most likely to be m -cresol. i.e. Thus, the overall reactions are as follows.
