Question -

Choose correct option:-

Options:

A . Anisole when treated with

c o n c . H N O_{3} & c o n c . H_{2} S O_{4},

major product is 3-nitro anisole.

B . Acetylation of salicylic acid gives aspirin

C . ^{$^{-} C H C l_{2}$ is nucleophile attacking the $s p^{2}$ hybridised carbon in phenoxide ion in Reimer-Tiemann reaction.}

D . Phenol 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.
