Which of the following reactants is used for the preparation of ethyl benzene, where anhy. AlCl 3 is a catalyst?
Options
- ACH 3 · CH 2 · OH + C 6 H 6
- BCH 3 - CH = CH 2 + C 6 H 6
- CH 2 C = CH 2 + C 6 H 6
- DCH 3 - CH 3 + C 6 H 6
Correct answer
C. H 2 C = CH 2 + C 6 H 6
Step-by-step solution
Fridel crafts Alkylation of Benzene takes place when ALkyl halide reacted with Benzene in presence of Anhydrous AlCl 3 . Now Alkenes can form Alkyl Benzene in Industrial process. The process involves the reaction of Benzene and Ethylene in presence of an Anhydrous AlCl 3 catalyst promoted by HCl . The H 2 C = CH 2 + C 6 H 6 on reaction produce ethyl benzene as follows
