C6H6 + CH2 = CH2 → AlCl3 → ?

1. C6H5CH2CH3
2. C6H5CH3
3. C6H5CH2CH2CH3
4. C6H5CH2CH2CH2CH3

Correct answer: C6H5CH2CH3

Solution

The reaction involves the Friedel-Crafts alkylation of benzene (C6H6) with ethene (CH2=CH2) in the presence of AlCl3, which acts as a Lewis acid catalyst. This results in the formation of ethylbenzene (C6H5CH2CH3).
