1. An organic compound gives white precipitate with bromine water means it must be a phenol. From the molecular formula it is identified as C6H5OH.
2. Phenol on reaction with NaOH gives (B) as sodium phenoxide C6H5 ONa.
3. Sodium phenoxide on reaction with methyl iodide in the pressure of dry ether undergo Williamsons synthesis and gives Anisole as (C).
4. Anisole on reaction with acetyl chloride undergoes Fnedel Craft’s acetylation and yield O – methoxy acetophenone and p-methoxy acetophenone as (D) and (E).
