Master Organic Chemistry LLC Avis 

The website was great, it wasn't over complicating or anything, it gives the resources for O-chem directly. The multitude of questions and types of questions they offer can help any students prepare for anything thrown at them in O-chem.

Super super helpful. Probably the only reason I got an a in orgo. The practice problems had a nice range in difficulty and were easy to follow with the explanations provided!! Would recommend

Fun and accessible way to brush up my synthetic repertoire! Somehow much more fun and engaging that stuffing Clayden's textbook in my head

Got me through org chem 1 and 2. Absolutely amazing content

It was easy to use. And the information was really detailed and easy to understand. This is a really good platform for understanding organic chemistry.

MOC helped me learn organic chemistry basics in just one month and I was able to pass my exam just because of this site. I really recommend this website if you have one of those teachers that just can't explain the information properly in a way it where it clicks for you. Even youtube couldn't help me. I love that everything is explained very narrowly and precisely. The way reactions and examples of them are presented helped me recognise the patterns and understand how OC works very quickly. I don't need chemistry in my studies anymore, but this site is probably even more helpful if chemistry is your major.

I used this website for my organic chemistry 2 course, but it was also helpful when reviewing old concepts from orgo 1. My professor barely taught us anything but I was able to teach the entire course to myself using just this as my resource. Thank you so much for the simplified and clear explanations and diagrams. I ended with a 95 in the class :)

I really appreciated both the clear explanation of the mechanisms and the many guided exercises to practice with. It's a much clearer and more intuitive approach to studying organic chemistry compared to the methods I had used before. It helped me through 2 exams I had been struggling with for a long time.

Very accessible and content is very similar to that on the exam. Overall made o-chem fun and easy to understand.

MOC makes learning Organic Chemistry 1 & 2 so much easier. With its comprehensible explanations and illustrations, I was finally able to understand what was going on in class! MOC made me more confident in class and improved my grades significantly. I promise you will not regret!

It has helped me to start having hope in learning organic chemistry! It was once a subject I wanted to give up. After searching and trying many different organic chemistry books, I can say master organic chemistry is the easier to grasp and understand the complicated ideas OG. I'm happy to recommend this to everyone!!

Hands down, one of the best Chemistry resources I’ve ever come across.
As a Chemistry teacher, I’m extremely particular about the resources I use and recommend to my students. I pay close attention to the accuracy of the content, the depth of the concepts, the way they’re explained, and especially the quality of the questions — and Master Organic Chemistry consistently delivers.
What I love most is how well the concepts are broken down. The explanations are clear, precise, and actually build understanding, rather than encouraging students to simply memorize information. The questions are equally strong and make students genuinely think and apply what they’ve learned.
I’ve used and reviewed a lot of Chemistry resources over the years, and this is easily one of my favourites and one I confidently recommend to my students.
An exceptionally well-written and thoughtfully created Chemistry resource. Absolutely love it.

I mainly used the notes to revise for my University exams. They were extremely helpful in covering topics I needed a second explanation for. The diagrams are amazing and help convey the information well. I haven’t seen another online set of notes like this online. I used it for 3 months and would definitely recommend.

I teach Organic Chemistry and have recommended this website to the students as a supplementary material for at least 7 years!
The website is an excellent resource - this is the only website I recommend to students whether they are learning intro org in gen chem or Org 1 and 2. Each topic is thoroughly-researched with original literature cited, but the content is not presented in a dry, jargon-y way. It is updated regularly with novel insights. The topics are well organized, the figures are clear and beautiful, and challenging concepts/mechanisms are broken down into understandable parts. James also ensures that the concepts are contextualized - why should students learn this reaction? Finally, apart from the content being excellent, the website is also very entertaining. I love the cultural references, history of science detours, and, especially, the stereochemistry cat!

Master Organic Chemistry is the best online resource for supporting student (and faculty!) learning. I have been using MOC with my Organic Chemistry 1 & 2 courses for several years now. The students love the content and extra study resources, but most importantly it is the most current, accurate, and understandable resource out there. The text is very conversational, so you feel like you are part of the story and the figures and images are very clear and informative. Better than any textbook!

amazing website!! super useful for chemistry uni

Phenomenal resource for undergrad ochem for me. Everything is organized has neat reaction sequences and arrows and has details about important rules or useful rules of thumb. I’d recommend it to anyone who needs an O-chem reference tool

I really enjoyed all of the articles that were provided as well as the quizzes and relatable humor. Once I got the membership, the cheat sheets were so awesome, I had it pinned in my browser at all times… lol.
My only thought would be to include videos, covering the content in the articles because I personally learn much better with videos rather than reading.
Overall I loved the site and recommend it to anyone who needs help in chemistry!

MOC was incredibly helpful during my accelerated summer Organic Chemistry II course. It presented the material in a much more concise way than my textbook. The Organic Chemistry II summary in 19 pages was especially helpful because I was taking the entire course in only five weeks. The diagrams, charts, and reactions summaries helped me to elucidate the key information from the chapters covered in my textbook. I also found the Reagents Guide extremely useful. There are so many reagents in Organic Chemistry II, and some can be used in several different ways, so having them organized into an index made studying the reactions much more manageable. I would definitely recommend MOC to anyone taking Organic Chemistry!!!

Very good information. Owner is also very receptive and communicative to subscription updates and improvement suggestions. Highly reccommend if you need a source to learn Organic Chemistry.
