The synthesis of anisole has to be illustrated using benzene as the starting compound. Concept Introduction: Benzene is a stable aromatic compound and it is the simplest form of the aromatic compounds . It is a very versatile compound that it furnishes various products with various reagents. The most common type of reactions that benzene undergoes is electrophilic substitution reactions. The various types of electrophilic substitution reactions in benzene are – Chlorination, Bromination, Nitration, Sulfonation, Friedel Crafts Alkylation/Acylation etc. So it is clear benzene can be converted to various range of compounds with appropriate reagents and reaction conditions. One of the useful method one can adapt to introduce any kind of group or atom onto the benzene ring is electrophilic substitution reaction. Aromatic compounds undergo another type of reactions called elimination – addition reaction. A compound with leaving group when treated with a strong base under high or low temperature undergoes elimination – addition reaction where the leaving group is eliminated and a new group is added. Halogens are known to be best leaving groups.

I have a question about this problem involving mechanisms and drawing curved arrows for acids and bases. I know we need to identify the nucleophile and electrophile, but are there different types of reactions? For instance, what about Grignard reagents and other types that I might not be familiar with? Can you help me with this? I want to identify the names of the mechanisms for problems 1-14, such as Gilman reagents and others. Are they all the same? Also, could you rewrite it so I can better understand? The handwriting is pretty cluttered. Additionally, I need to label the nucleophile and electrophile, but my main concern is whether those reactions differ, like the "Brønsted-Lowry acid-base mechanism, Lewis acid-base mechanism, acid-catalyzed mechanisms, acid-catalyzed reactions, base-catalyzed reactions, nucleophilic substitution mechanisms (SN1 and SN2), elimination reactions (E1 and E2), organometallic mechanisms, and so forth."
