WebQuestion Benzene reacts with acetyl chloride in presence of anhydrous aluminium chloride to form : A Acetophenone B Phenyl acetate C Chlorobenzene D Benzoic acid Hard Solution Verified by Toppr Correct option is A) The given reaction is Friedel-Craft's acylation reaction. WebAnhydrous AlCl 3 is used as a catalyst in Friedel Craft reactions. Friedel Craft reactions are reactions involve thee attack on electrophile on the aromatic ring. It is an electrophilic …
WebThe attacking electrophile is an acylium ion (RC ≡ O+) made available by the reaction of acid halide and an anhydrous lewis acid. This reaction occurs by. (i) Formation of ayclium ion. (ii) Formation of Wheland intermediate. (iii) Removal of proton from the intermediate. Here, benzene reacts with CH3COCl in the presence AlCl3 to give C6H5COCH3. WebThe reaction is completed by deprotonation of the arenium ion by AlCl 4−, regenerating the AlCl 3 catalyst. However, in contrast to the truly catalytic alkylation reaction, the formed …
