Students get stuck because they can't see which specific section of the chapter a problem maps back to.
This is a great request. Petrucci's General Chemistry (often General Chemistry: Principles and Modern Applications ) is a famously dense, rigorous textbook. A good feature needs to address a specific pain point for students using this book: and visualizing multi-step concepts . petrucci general chemistry
