The molecule in question was a substituted cyclohexane with three chiral centers. In the book’s world, known as The Labyrinth , molecules were not just structures; they were riddles. Every chapter was a fortress: GOC (General Organic Chemistry) was the gatehouse, where inductive and mesomeric effects threw spears at careless students. Hydrocarbons was a dragon’s den of Markovnikov and anti-Markovnikov fire. He checked the answer
But Aryan had learned a secret from M.S. Chauhan: Read the footnote. Read the exception. Aryan had already survived those
The problem was a trap. The first step was a simple ozonolysis. Easy. The second was an aldol condensation—messy, but manageable. The third was a Wittig reaction. That’s where most students died. They would draw the wrong E/Z isomer, forgetting the subtle steric dictates of the ylide.
The molecule in his mind twisted. Bonds rotated. The chair flip happened. And suddenly, the mess of dashes and wedges collapsed into a single, elegant, meso compound.
