Really helpful, clearly laid out the concepts and was interactive so I got some practice doing the problems too. Made it less confusing by going through everything systematically and then summarizing what the take away should be at the end of the each section. The only annoying thing was having to do the elimination chapter on my own, I bought the book to help me study and I prefer the person tell me what I need to know so then I can just practice it. Still super helpful though

“let’s compare organic chemistry to a game of chess” a statement you should have totally lead with rather than waiting until the very last page to get me excited. 100000/10 where would I be without this book I don’t know. in the wise words of Taylor Swift, checkmate, I couldn’t lose ‼️

This book was extremely helpful in my first semester of chemistry. The first half of the book was much more helpful than the second half. At first I thought the way the author wrote it was kind of amusing.. then it just got annoying. All in all definately worth it.

Somehow explains chemistry in a way that conveys the beauty and simplicity of the science

not your traditional textbook. definitely helpful (especially when you don’t understand your professor’s slides). wish me luck on my midterm tomorrow.

This book was not exactly what I expected, but was interesting and provided a good foundation for understand OC. Lots of memorization that probably required for a college student, but because I only had a passing interest, I did a lot of flipping back and forth to work problems in some chapters. The concepts, not being a science guru, were sometimes needed rereading of chapters, sometimes three rereads to grasp the concepts. I feel that after a casual reading that I have a good grasp and would not have any problems if I were to take an OC class.

This book is the reason I’m doing well in orgo so far. It is my best friend, my support system, my favorite little puzzle book <3
The only downside is I finished it, but the block isn’t over so I don’t know what I’m gonna do for the rest of the content we still have???? Help?!????

This book has changed my life and I'm only on the 3rd chapter. I am now excited about (vs terrified of) O-Chem.

I read the first sections of this book in like the week before I began my O-chem course this semester and found them extremely helpful in building me a foundation and getting me comfortable with resonance and mechanisms, etc. It is formatted in an accessible way and all of the concepts are presented in a way that is easy to understand (especially compared to your textbook).

My advice for making the most of this: read it, take your notes on it, but most importantly take advantage of all of the practice problems which are excellently explained and planned. Then, go through your assigned textbook and take extra notes on the content this skips over AND complete the practice problems in your textbook, which are more complicated/specific/advanced applications of the concepts this book covers. It’s a lot, but you will feel very comfortable on your tests.

My course deviated from this book right around when it starts to go into electron geometry, and I wasn’t able to keep up with both and didn’t find it quite as helpful there. I came back later and did some of the chapters on reactions, and found it somewhat helpful, but not as helpful as the first few chapters were.

Overall, I recommend this book if you want to build a solid understanding of chemistry and be confident on your tests.

A bit outdated, as it recommends photocopying certain pages for practice, but the concepts are well explained. Naturally the first half was a quicker read than the second half, but the concepts built on each other pretty well. I wish there had been a bit more repetition for people who didn’t read the book all in a day or two.

Another turning point, a fork stuck in the road
Time grabs you by the wrist, directs you where to go
So make the best of this test, and don't ask why
It's not a question, but a lesson learned in time

It's something unpredictable
But in the end, it's right
I hope you had the time of your life

This is designed to be used along with a chemistry course.
This is not meant to teach someone chemistry on its own.

You WILL learn organic chemistry. Don't forget 2nd semester topics though!

Excellent guide for those who want to get extra practice problems. The explanations are to the point and Klein does a great job of going through and thoroughly explaining the material covered over the course. Problems are embedded within the material so you're practicing as you learn. Additional problems are found at the end of chapters to synthesize information covered in the chapter. Answers with explanations for all (yes all) problems are included at the back of the book. Can't recommend enough for those taking organic chemistry 1.

3.5 stars.

This is the second book I have read about organic chemistry - and I must say, this one was a lot better than the first. David Klein's intent is to help readers build intuition behind the subject and he does a very good job of doing just that.

Really, the first 9 chapters of this book are very good. My only issue is with the last 4 chapters, which are unfortunately pretty useless: for whatever reason, Klein switches gears and basically says, "Well, I've taught you how to think about substitution and elimination reactions, so use these blank pages to copy down the additional mechanisms you can find in any other chemistry text and commit them to memory." It's very bizarre, especially because Klein has a gift for explaining this stuff. My theory is, he was getting sick of writing the book or maybe didn't have time for it: seriously, the last 4 chapters probably took a single weekend to write.

I may read the sequel. More of the same, I'm guessing.

I took Organic Chemistry 1 in an accelerated five week session and I barely had time to read the actual textbook to get the information I needed to understand the material. This guide cut everything that was unnecessary and cut to exactly what was crucial to the reactions and mechanisms we needed to thoroughly comprehend. I HIGHLY recommend this supplement to the textbook. It has sample problems also that proved very useful. I would almost say that it could replace the textbook and solutions manual but there are just aren't enough problems to practice in this text alone which make the full textbook and solution manual necessary. Unlike the solutions manual, this short guide does NOT provide explanations alongside the answer keys.

This book is simply genius. Don't take an organic chemistry class without taking this book with you. All of the concepts are explained in layman's terms and there are practice problems to help with further understanding the material. I absolutely adore this book and it is a great supplement to any organic class. Happy studying!

This was hands down the most helpful book I bought for Organic Chemistry. Literally a lifesaver. This explains concepts in ways that my textbook did not illustrate. It is very explicit and visual with corresponding worksheets inside to quiz yourself. The worksheets were more helpful than my actual assigned homework for Honors Organic Chemistry 1.

*2021 Around the Year Reading Challenge*
Prompt #47: A nonfiction book other than a biography, autobiography or memoir


Counting this book for my reading challenges because, contrary to how it looks, this book was not required reading and I picked it up a few months ago to gain some more understanding to a subject I like but never fully understood.
