Question

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 (A) benzyl alcohol and 2, 4, 6-tribromo-3- methoxy benzene (B) benzyl alcohol and 2, 4, 6-tribromo-3-methyl phenol (C) o-cresol and 3, 4, 5-tribromo-2-methyl phenol (D) methoxybenzene and 2, 4, 6-tribromo-3- methoxy benzene

Compound X (C7H8O) 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:

Q. An organic compound $(X)$ with molecular formula, $C_{7} H_{8} O$ is insoluble in aqueous $N a H C O_{3}$ but dissolves in $N a O H$ . When treated with bromine water $(X)$ rapidly gives $(Y), C_{7} H_{5} OB r_{3}$ . The compounds $(X)$ and $(Y)$ respectively, are

benzyl alcohol and $2, 4, 6$ -tribromo- $3$ - methoxy benzene

benzyl alcohol and $2, 4, 6$ -tribromo- $3$ -methyl phenol

$o$ -cresol and $3, 4, 5$ -tribromo- $2$ -methyl phenol

methoxybenzene and $2, 4, 6$ -tribromo- $3$ - methoxy benzene

$m$ -cresol and $2, 4, 6$ -tribromo- $3$ -methyl phenol

Compound X $(C_{7} H_{8} O)$ insoluble in aqueous $N a H C O_{3}$ but soluble in $N a O H,$ 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:

o-cresol and 3,4,5-tribromo-2-methyl phenol

methoxybenzene and 2,4,6-tribromo-3- methoxy benzene

m-cresol and 2,4,6-tribromo-3-methyl phenol

Compound X (C7​H8​O) 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:
