The days turned into weeks, and Alex found herself looking forward to each new practice problem. She started to see the beauty in the complex reactions and the clever strategies that Dr. Thompson had designed to help them learn.

As Alex continued to work through the practice problems, she encountered many more challenges. However, with each solved problem, her confidence grew. She began to appreciate the intricate relationships between different concepts in organic chemistry and developed a deeper understanding of the subject.

Just as Alex was about to give up, she remembered a crucial concept from her previous lecture: the use of silicon-based reagents in organic synthesis. A lightbulb went off in her head, and she quickly jotted down a possible mechanism.
