## What is Organic Reactions?

This app allows people working in organic chemistry for a quick access to the main functional group reactions and their mechanisms. 
The application is organized to provide a direct link between a reactant and its corresponding product, as well as the synthesis and protection reactions.

To enable a regular updating and to support this work, some of the functions, and a list of reactions sorted by name requires an additional purchase.

If you have any problem, do not hesitate to send me an email, by explaining the nature of your problem and your phone model.

### 5/5 — Why I think this is the best app!

*2025-11-18, version 2.6*

I try to get the perfect app to study organic chemistry until I found this app I fought that it was going to ask me some questions about organic chemistry but it’s just a helpful app to use!

### 5/5 — EDIT: Thanks!

*2024-03-11, version 2.6*

EDIT: Everything is working great now!

### 5/5 — Mechanisms and free plan

*2023-11-04, version 2.4*

Complete mechanisms for all of reactions and synthesis. 
Make alcohol and other parts free.

### 3/5 — ⭐️⭐️⭐️

*2023-06-03, version 2.4*

I like it I really do but to make it more fun you mite want to ad a quiz button and no in app purchases.

### 5/5 — Super helpful w/ memorization

*2023-04-01, version 2.4*

This app is super helpful for memorizing reagents for reactions and synthesis. I wish I knew about it when I was taking orgo 1!

### 5/5 — Great overview

*2023-03-08, version 2.4*

This app gives a great overview of possible reactions. Thanks for your work on this

### 5/5 — Helpful!

*2022-11-30*

Thankful for this app!

### 5/5 — Use to have Flashcards functions?

*2022-09-21, version 2.3*

Great app but didn’t this use to have Flashcards or quizzes ?

### 4/5 — ❤️❤️

*2021-07-24, version 2.3*

ارجعو تحديث التطبيق فهو رائع لجعل شكله اجمل و اسهل استخداما

### 5/5 — I am blown away

*2021-07-22, version 2.3*

This app is extremely easy to use! Very useful! You may have to pay 3 dollars to get the carbonyl reactions, however it has plenty even without that! Where was this when I took organic 1 and 2!
