Question: What is the main product of the reaction of benzene with bromine in the presence of FeBr3?

Options:

Correct Answer: Bromobenzene

Solution:

The reaction of benzene with bromine in the presence of FeBr3 leads to the formation of bromobenzene through electrophilic aromatic substitution.

What is the main product of the reaction of benzene with bromine in the presence of FeBr3?

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.
