Chemistry As A Second Language: A Practical Guide
The Chemistry As A Second Language series by Mark D. Rosenberg is exactly what the title promises: a set of workbooks that walk you through general and organic chemistry topics in a very conversational style. They're not textbooks. They're supplementary practice materials with short explanations followed by problems. If you're already sitting through a lecture course and just need someone to rephrase things without all the dense prose, these books fill that gap. If you're trying to self-study from scratch with zero background, you'll still need to go to a primary resource first. Most people using these workbooks are students who already have some exposure to the material but keep tripping over the same conceptual hurdles. The organic chemistry book covers mechanisms, resonance, stereochemistry, and reaction types in a way that forces you to draw structures rather than memorize them. The general chemistry companion handles stoichiometry, equilibrium, thermodynamics, and gas laws. The writing style is deliberately simple, sometimes almost blunt, which makes the content accessible without dumbing it down too far. I found the organic chemistry volume particularly useful during my second semester when I was struggling with reaction mechanisms. The book doesn't just present reactions; it makes you draw every step. That's the core methodology. You read a short section on something like SN1 versus SN2, then immediately work through problems where you identify nucleophiles, leaving groups, and the geometry of the transition state. The repetition builds pattern recognition, which is genuinely what matters in organic chemistry.
The general chemistry companion follows the same structure but the problems can get repetitive at times. Some sections feel padded, especially around unit conversions and basic mole calculations. I skipped roughly a third of those early chapters and came back only when my homework set had a problem I couldn't crack. That's a reasonable strategy. You don't need to do every single exercise if you already understand the concept.
How to Use These Workbooks Effectively
Start with the chapter that corresponds to whatever topic your professor is currently covering. Read the explanatory text once through without stopping to highlight everything. Then do the problems on your own before looking at the answers. The answer key is included in the back, and it shows full worked solutions, which is useful for checking your work but also very tempting to abuse. Resist that. Looking at the solution before attempting the problem undermines the whole point of the workbook. For the organic chemistry book specifically, keep a sheet of scratch paper nearby and actually draw every mechanism. Don't trace over existing structures. Draw them yourself from memory after reading the explanation. This is where the book differs from most textbooks. Textbooks show you the answer. These workbooks make you produce the answer. It feels slower at first, but it compounds quickly over the course of the semester. One edge case I ran into involves stereochemistry notation. The book uses standard wedge-and-dash conventions, but the exercises don't always make explicit whether you're working in a specific solvent or temperature range when determining whether a reaction proceeds with retention or inversion. I hit this in a problem set involving neighboring group participation. My initial answer had the wrong stereochemical outcome because I assumed an SN2 pathway when the conditions actually favored an SN1 mechanism with ion pair collapse. The workaround was straightforward: I went back to the chapter on stereochemistry and cross-referenced the solvent effects table the book provides in the appendix, then reworked the problem with the correct mechanism identified first. This happened maybe three or four times across the entire book, but each time it revealed a genuine gap in my understanding rather than a flaw in the material itself.

Limits and Where the Series Falls Short
These workbooks are not comprehensive. They don't cover every topic you'll encounter in a full university course. Spectroscopy gets very brief treatment in the organic volume, and the general chemistry companion has almost nothing on electrochemistry beyond standard half-reaction balancing. If your course requires fluency in NMR interpretation or cyclic voltammetry, you'll need supplementary resources. The writing can also be overly simplistic in places. Rosenberg occasionally skips steps that experienced students might find trivial but that beginners genuinely need spelled out. For example, the treatment of significant figures in stoichiometry is cursory. If you're taking a lab course alongside the lecture, this matters. You'll want to pair the workbook with a dedicated lab manual or a more detailed reference for quantitative analysis. There's also the issue of problem variety. The exercises tend to repeat the same pattern within each chapter. After you've done ten similar problems, the eleventh won't teach you anything new unless you're specifically targeting a weakness. In that case, move on to a different resource for additional practice. LibreTexts or the OpenStax textbook have problem sets with more variation at no cost.
Where to Get It
The Chemistry As A Second Language books are published by Wiley. The most common editions are the third editions for both the general chemistry companion and the organic chemistry text. You can find them on Amazon, Barnes & Noble, and directly from Wiley's website. Prices vary, but they typically run between twenty and thirty dollars for paperback. If you're on a tight budget, the older second editions are functionally identical for most course content, since the core pedagogy hasn't changed significantly between editions. Used copies circulate on campus bulletin boards and online marketplaces frequently enough that you shouldn't have trouble finding one. If you prefer digital, the books are available as PDFs through most academic retailers. There's no official free version, but many students scan their copies and share them through unofficial channels. I don't recommend pursuing those routes unless you're comfortable with the legal and ethical implications. The books are inexpensive enough that buying a used copy is usually the simplest path.
A Few Technical Notes Worth Knowing
The organic chemistry workbook uses curved arrow notation consistently, which is important because many introductory textbooks switch between different styles. If you're comfortable with the notation Rosenberg employs, transferring that skill to other resources will be easier. The book also uses IUPAC nomenclature throughout, so you won't encounter confusing common names mixed in unexpectedly. One counter-intuitive point that beginners often miss: the order of chapters in the organic volume doesn't strictly follow the sequence most professors use. Resonance comes before substitution and elimination, which is pedagogically sound but might frustrate someone trying to align the book with their syllabus. Check the table of contents against your course schedule before committing to using it as your primary supplement. If the chapter order doesn't match, you'll waste time flipping back and forth or skipping ahead and coming back later. Another nuance is that the general chemistry companion treats gas laws and thermodynamics with more depth than many supplemental resources do, but it glosses over kinetics. If your course emphasizes reaction rates and rate laws, plan to find additional material for that section. The organic book handles kinetics better because it integrates rate-determining steps into mechanism discussions, but the general chemistry volume largely sidesteps it.
These workbooks work best when you're already somewhat familiar with the material and need to solidify your understanding through active practice. They're not meant to replace a textbook or lecture notes. Think of them as a bridge between passive reading and exam performance. If you use them that way, they deliver what they promise. If you expect them to teach you everything from scratch, you'll be disappointed. The gap between not knowing anything and being able to solve these problems is larger than the books themselves account for. Pair them with a proper textbook, attend lectures, and do the extra practice problems from your course materials when the workbook runs out of fresh material for a given topic.
