Remove HCl and AlCl3 (hydrochloric acid). When benzene is react with CH3OCl in the presence of Alcl3. (i) Benzene reacts with acetyl chloride in the presence of anhydrous AlCl3 to give acetophenone. Acetophenone have molar mass – 120.15 g/mol. How to convert benzene to acetophenone? Expert Answer: Reaction of benzene with acetyl chloride in the presence of a Lewis acid such as (anhydrous aluminum chloride ,AlCl 3) produces acetophenone. HNO3 in the presence of conc. Students (upto class 10+2) preparing for All Government Exams, CBSE Board Exam, ICSE Board Exam, State Board Exam, JEE (Mains+Advance) and NEET can ask questions from any subject and get quick answers by subject teachers/ experts/mentors/students. 1 answer. When acetophenone react with a solution of in an alkaline medium such as NaOH or KOH then it gives sodium benzoate as a product. When benzene react with CH3Cl (methyl chloride) in the presence of AlCl3, then it give methyl benzene (C6H6-CH3). Benzene is gives electrofilic substitute reaction. In this reaction, CH3 attack on H+ of benzene because you know that benzene have six carbon and six hydrogen. (a) How will you bring about the following conversions? Welcome to Sarthaks eConnect: A unique platform where students can interact with teachers/experts/students to get solutions to their queries. you know that, Methyl (CH3) is electrophile where as chloride (Cl) is necluphile. 6H 2O, SnCl 2.

Acetophenone boiling point 200°C and melting point 19-20°C. In this process, benzene is given product directly. Acetophenone is also used as a regent, for manufacturing of perfumes and different type of body perfumes. The conversion of acetic acid over H-ZSM-5 and H-mordenite are found to be 42.6 and 7.2 wt%, respectively. Turbidity Measurement (new update content), Natural dyes for textile goods (new update content), h2o molar mass with latest update information, Nitrobenzene With Latest and Interesting Information, Nitrobenzene to benzoic acid with good concept article. In this reaction, a solution of in an alkaline medium such as NaOH or KOH is act as an oxidizing agent. Reaction of benzene with acetyl chloride in the presence of a Lewis acid such as (anhydrous aluminum chloride ,AlCl3) produces acetophenone. Acetophenone occurs from naturally (fruits). In this reaction, Cl Chloride attack on carbon (C) because (Cl) chloride and (C) carbon both have negative then finely it give toluene as a product. H 2 SO 4 to give nitrobenzene which further reacts with chlorine in the presence of anhydrous AlCl 3 to give m-nitro chlorobenzene. Acetophenone are windly use in manufacturing of pharmaceutical industry and madicine. (iv) Benzene can be converted into acetophenone as: ← Prev Question Next Question → Related questions +1 vote. Acetyl chloride acts as a reagent for the preparation of esters and amides of acetic acid. We know that CH3 act as a positive charge. Remove HCl and AlCl3 ( hydrochloric acid) In this reaction, methyl CH3 have positive charge where as chloride have negative charge as shown on figure. It is connected each other.
