Choose correct option:- Options: A . &nbspAnisole when treated with conc. HNO3 & conc. H2SO4, major product is 3-nitro anisole. B . &nbspAcetylation of salicylic acid gives aspirin C . &nbsp −CHCl2 is nucleophile attacking the sp2 hybridised carbon in phenoxide ion in Reimer-Tiemann reaction. D . &nbspPhenol is commercially prepared from Dow’s process.

Answer: Option B : B Since methoxy group in anisole is activating and o & p-directing, major product is 2-nitro anisole & minor product is 4-nitro anisole. Acetylation of salicylic acid gives aspirin. Reimer-Tiemann reaction in presence of C H C l 3 & a q . N a O H with phenol leads to attack of electrophile + C H C l 2 on s p 2 hybridised carbon in phenoxide ion. Phenol is commercially prepared from oxidation of cumene followed by treatment with acid. This reaction leads phenol & acetone as by-product in large quantities. Dow’s process involves treatment of Chlorobenzene with fused N a O H under high pressure conditions followed by acidification.
