How will you convert benzene to the following? 

i) Ethyl phenyl ketone 

ii) p- Bromobenzyl bromide 

i) Ethyl phenyl ketone can be synthesized by the Friedel-Crafts acylation reaction, which involves the acylation of benzene with an acylating agent in the presence of a Lewis acid catalyst. The general mechanism is as follows:

1. Activation of the acylating agent: The acylating agent, such as ethyl chloride or ethyl bromide, is activated by reacting with the Lewis acid catalyst, such as aluminum chloride (AlCl3), to form an acylium ion intermediate.
