Using anhydrous AlCl3 as catalyst, which one of the following reactions produces ethylbenzene (PhEt)?

1. H3C-CH2OH + C6H6
2. CH3-CH=CH2 + C6H6
3. H2C=CH2 + C6H6
4. H3C-CH3 + C6H6

Correct answer: H2C=CH2 + C6H6

Solution

Ethylbenzene (PhEt) is formed via the Friedel-Crafts alkylation reaction. Ethene (H2C=CH2) reacts with benzene (C6H6) in the presence of anhydrous AlCl3 to form ethylbenzene.
