An organic compound 'X with molecular formula, C7H8O is insoluble in aqueous NaHCO3, but dissolves in NaOH. When treated with bromine water 'X' rapidly gives 'Y, C7H5OBr3. The compounds 'X' and 'Y' respectively, are
benzyl alcohol and 2,4,6-tribromo-3-methoxy benzene
m-cresol and 2,4,6-tribromo-3-methyl phenol
benzyl alcohol and 2,4,6-tribromo-3-methyl phenol
o-cresol and 3,4,5-tribromo-2-methyl phenol
B.
m-cresol and 2,4,6-tribromo-3-methyl phenol
Compound' X' (C7H8O) is insoluble in aqueous NaHCO3 but soluble in NaOH, so it is a phenol. Since the number of carbon atoms remains the same after bromination, the compound must be meta cresol and reactions takes place as follows :
