Question: A research chemist is synthesizing a complex heterocyclic compound 'Z' starting from a simpler nitrogen-containing heterocycle 'X' (CHN). The synthesis involves several distinct steps, each incorporating a different reaction mechanism. The sequence of the synthesis is as follows: Compound 'X' is first nitrated to form compound 'Y'. Compound 'Y' then undergoes a Suzuki coupling reaction with a boronic acid derivative. The product of the Suzuki coupling is treated with a reducing agent, leading to the reduction of the nitro group. Finally, the reduced product undergoes a cyclization reaction in the presence of an acid catalyst to yield the final product 'Z'. Based on this sequence of reactions, determine the most likely class or structural feature of the final product 'Z'. Options: A. A polycyclic aromatic hydrocarbon B. A nitrogen-containing bicyclic compound C. A substituted pyrrole D. A pyridine derivative Hints: Consider the starting structure implied by CHN and its potential transformation through each step. Reflect on the types of reactions, such as nitration, Suzuki coupling, reduction, and acid-catalyzed cyclization, and how they modify molecular structures. Think about the typical outcomes of these reactions in the context of heterocyclic chemistry. Don't use chatgpt otherwise I will give you disupvote
