benzene

What is the structure of benzene?

Benzene is a six-carbon ring with alternating double bonds, often represented with a circle indicating resonance.

How is benzene produced?

Benzene can be produced through various methods including crude oil refining, coal carbonization, and from the chemical compound toluene.

What are some reactions that benzene undergoes?

Benzene undergoes electrophilic aromatic substitution reactions, such as halogenation, nitration, sulfonation, and Friedel-Crafts alkylation/acylation.

What is the general mechanism for electrophilic aromatic substitution?

In electrophilic aromatic substitution, the aromatic ring acts as a nucleophile, attacking an electrophile and forming a sigma complex, which then loses a proton to restore aromaticity.

What can benzene be reacted with in electrophilic aromatic substitution?

Benzene can react with halogens (e.g., $Cl_2$, $Br_2$), nitric acid (for nitration), sulfuric acid (for sulfonation), and acyl chlorides (for Friedel-Crafts acylation).
