It is typically very difficult to do a substitution reaction on an aromatic ring when the
leaving group is flanked by two other bulky substituents. Moreover, in Section 22.3, we
found that nucleophilic aromatic substitution requires strongly electron-withdrawing
groups on the benzene ring. However, Pd-catalyzed coupling allows entry into such
products. As examples, write the products of the following reactions and state which
coupling reaction is being utilized.

The ethylation of benzene is an electrophilic substitution reaction.
Identify the electrophile in the reaction.
Write the equation including reagents and conditions for the ethylation of benzene to produce ethylbenzene.
Hence outline the mechanism for the reaction.
Ethane reacts with chlorine (Cl2) in the presence of ultra-violet (UV) light, to produce 1-chloropropane (CH3CH2Cl) and hydrogen bromide (HCl). As shown in the equation below.CH3CH3+ Cl2→ CH3CH2Cl+ HClDescribe the reaction mechanism of the reaction between ethane and chlorine to produce 1-chloroethane. The description should be detailed and must include the type of bond fission that takes place. You may sketch and insert suitable diagrams to aid your description if you wish.

- Alkynes do not react directly with aqueous acid as do alkenes, but will do so in the presence of mercury(II) sulfate as a Lewis acid catalyst. The reaction occurs with Markovnikov regiochemistry, so the OH group adds to the more highly substituted carbon and the H adds to the less highly substituted carbon. The initial product of the reaction is a vinyl alcohol, also called an enol. The enol immediately rearranges to a more stable ketone via tautomerization.
