Q: What is the main product of the reaction of benzene with bromine in the presence of FeBr3?
Solution: The reaction of benzene with bromine in the presence of FeBr3 leads to the formation of bromobenzene through electrophilic aromatic substitution.
Steps: 8
Step 1: Start with benzene, which is a ring of six carbon atoms with alternating double bonds.
Step 2: Introduce bromine (Br2) to the benzene. Bromine is a diatomic molecule made of two bromine atoms.
Step 3: Add FeBr3, which is iron(III) bromide. This compound helps activate the bromine for the reaction.
Step 4: The FeBr3 interacts with the bromine, making it more reactive. This creates a bromonium ion.
Step 5: The bromonium ion then reacts with the benzene ring. One of the carbon atoms in the benzene donates an electron to the bromonium ion.
Step 6: This forms a new bond between the benzene and one of the bromine atoms, creating bromobenzene.
Step 7: The benzene ring loses one hydrogen atom in the process, which is released as a proton (H+).
Step 8: The final product of the reaction is bromobenzene, which has a bromine atom attached to the benzene ring.
