Final answer:
The structural formula for the product from Friedel-Crafts alkylation or acylation of benzene can vary depending on the specific compound used. An example reaction is the alkylation of benzene with ethyl chloride to form ethylbenzene.
Step-by-step explanation:
The structural formula for the product from Friedel-Crafts alkylation or acylation of benzene with each compound can vary depending on the specific compound used. However, I can provide an example to illustrate the process. Let's consider the reaction of benzene with ethyl chloride in the presence of aluminum chloride catalyst:
Benzene + Ethyl chloride → Ethylbenzene
In this reaction, the hydrogen atom on benzene is replaced by the ethyl group resulting in the formation of ethylbenzene.
