Answer» Solution :a 1. An organiccompoundgiveswhiteprecipitatewith bromicwatermeansit MUSTBE aphenolfromthe molecularformulait isidentified as `C_(6)H_(5)OH` 2. Phenol ONREACTIONWITH NaOH gives (b) assodiumphenoxide `C_(6)H_(5) ONa` 3. Sodiumphenxide on reactionwithmethyliodidein the pressureof dryetherundergoWilliamsonssynthesisand givesAnisoleas (C ) 4. Anisoleonreactionwithacetlychlorideundergoes Friedel Craftacetylationyield o-methoxyacetophenoneand p- methoxyacetphenone as (d ) and (E )
