Benzene diazonium chloride when warmed with water gives a compound, whose Sodium salt when reacted with Allyl bromide gives compound [ X ] . Identify [ X ] .

Step-by-step solution

Benzene diazonium chloride warmed with water Phenol ( C₆H₅OH ) + N₂ + HCl Phenol + NaOH Sodium phenoxide ( C₆H₅O^-Na^+ ) Williamson ether synthesis — sodium phenoxide reacts with allyl bromide ( CH₂=CH-CH₂Br ) via S_N2 : C₆H₅O^-Na^+ + Br-CH₂-CH=CH₂ C₆H₅-O-CH₂-CH=CH₂ + NaBr X is allyl phenyl ether: C₆H₅-O-CH₂-CH=CH₂
