i) Conversion of benzene to ethylbenzene:
To convert benzene to ethylbenzene, you can use an electrophilic aromatic substitution reaction known as Friedel-Crafts alkylation. The reaction involves the introduction of an ethyl group (C2H5) onto the benzene ring. Here's how you would carry out the conversion:

1. Start with benzene as your starting material.

2. Mix benzene with an alkylating agent, such as ethyl chloride (C2H5Cl), and a Lewis acid catalyst, typically aluminum chloride (AlCl3).
