12 points)When ethylbenzeneis treated with an electrophile, an electrophilic aromatic substitution reaction occurs in which the electrophile is installed exclusively in one position. Draw the structure of the resulting compound and use a series of resonance structures of the key intermediates to justify your given answer. FeBr3,Br2Answer should have the following: a. Structure and mechanism for the formation of electrophile, b.Attack of the electrophile and intermediates of attack (position para and meta) which follow, c.Resonance structures of intermediates that relate to para and meta attack.
