Question: What is the major product of the electrophilic substitution of benzene with bromine in the presence of FeBr3?

Options:

Correct Answer: Bromobenzene

Solution:

The major product is bromobenzene, formed when bromine reacts with benzene in the presence of a Lewis acid catalyst like FeBr3.

What is the major product of the electrophilic substitution of benzene with bromine in the presence of FeBr3?

Step 1: Start with benzene, which is a ring of carbon atoms with hydrogen atoms attached.
Step 2: Introduce bromine (Br2) to the reaction. Bromine is a diatomic molecule made of two bromine atoms.
Step 3: Add FeBr3, which is a Lewis acid catalyst. This helps activate the bromine for the reaction.
Step 4: The FeBr3 interacts with bromine, making it more reactive. This creates a bromonium ion.
Step 5: The bromonium ion then reacts with the benzene ring. One hydrogen atom from benzene is replaced by a bromine atom.
Step 6: This reaction forms bromobenzene, which is the major product.
