Reaction of alkyl halides with aromatic compounds in presence of anhydrous is known as

(A)Friedel–Craft's reactionCorrect
(B)Hofmann degradation
(C)Kolbe's synthesis
(D)Beckmann rearrangement

Answer: (A)

Solution

In the Friedel–Crafts alkylation reaction, an alkyl halide reacts with an aromatic compound in the presence of a Lewis acid catalyst such as anhydrous or , which generates an electrophilic carbocation (or polarised complex) that alkylates the aromatic ring: $Ar-H + R-X
