Problem 6 :
a) Write the balanced chemical equation for the hydrogenation of benzene (C₆H₆) using hydrogen gas (H₂) and a catalyst.
b) Explain why benzene undergoes substitution reactions rather than addition reactions.
Solution :
a) The balanced chemical equation for the hydrogenation of benzene (C₆H₆) is: C₆H₆ + 3H₂ → C₆H₁₂
b) Benzene undergoes substitution reactions rather than addition reactions because it is an aromatic compound with a stable resonance structure. The pi (π) electrons are delocalized, making it resistant to addition reactions. Instead, it undergoes substitution reactions, such as electrophilic aromatic substitution.
