What is required other than anhydrous AICI3 when toluene is prepared by Friedal craft reaction?
Correct answer: B. C6H6+ CH3Cl
- A. C6H6
- B. C6H6+ CH3Cl
- C. C6H5C2H5
- D. C6H5Cl and CH3Cl
Explanation
In the Friedel-Crafts reaction for toluene synthesis, anhydrous AlCl3 acts as a catalyst and requires the presence of benzene and CH3Cl. This combination leads to the formation of toluene. The other options provided do not include the correct combination of reactants necessary for the preparation of toluene via this reaction.

About Benzene and Aromatic Compounds
Benzene has a planar ring of delocalised π electrons, giving aromatic stability and equal carbon-carbon bond lengths. The topic covers resonance, electrophilic substitution reactions such as nitration, halogenation, sulphonation and Friedel-Crafts reactions, along with substituent effects and the distinction between substitution in benzene and addition in ordinary alkenes.
