Aldehydes contain the carbonyl group bonded to at least one hydrogen atom. Ketones contain the carbonyl group bonded to two carbon atoms. Aldehydes and ketones are organic compounds which incorporate a carbonyl functional group, C=O.

Anisole reacts with a mixture of concentrated sulfuric and nitric acids in nitration, yielding a mixture of ortho and para nitroanisole as the product.

Anisole undergoes Friedel-Crafts reaction with alkyl halide and acyl halide in the presence of anhydrous aluminum chloride as a Lewis acid catalyst. The reaction introduces the alkyl and acyl groups at ortho and para positions.

The alkoxy group is ortho, para directing, and activates the aromatic ring in a manner similar to phenol. In the halogenation of anisole, the methoxy group activates the benzene ring, allowing bromination to occur even without an iron (III) bromide ...

The order of reactivity is HI > HBr > HCl. Cleavage with concentrated HI or HBr at high temperatures results in the formation of tertiary halides when one of the alkyl groups is tertiary, following an SN₁ mechanism due to ...
