Is there a site that teaches all the mechanism of organic reactions in a very simple way?

Question

Because is so hard to understand from the textbook, or could you suggest a cheap book that can do it better.

Answer 1

So here is the deal with organic chemistry. It is a lot of material and can sometimes be difficult conceptually for a lot of people.

The common technique that students resort to is to just memorize every reaction they see. This has two flaws:
#1 There are just soooooo many reactions, really there are infinite reactions that can be proposed. It's just plain hard to remember when test time rolls around. Especially since everything is made up of C O N S H.

#2 On the test. I have dealt with many professors in organic chemistry both taking and in teaching. To varying degrees they like to put reactions on the exam that you have never seen before. Ones that you have to use your reasoning to explain. So all those memorized reactions are out the window.

The best approach is to build your knowledge from fundamentals and basics.

Go slow make sure you understand and if you don't ask!
You should ask why a lot. But you should start seeing patterns.

You need to be able to visualize in 3-D so if you can't get a model kit. Do this! This is a huge thing students do not do because they dont see the importance, but really it makes things a lot easier.

Learn Electrophiles and Nucleophiles and pay attention when they talk about Lewis Acid and Base chemistry. Fundamentally these and energy are what drives all of the reactions. So if you see a reaction you should try and reason out why it makes sense in terms of these.

Think of it like this an nucleophile (also called a lewis base) has a lone pair on it that it can donate . This will have a negative charge in general.

An electrophile ( also called a lewis acid) is an electron acceptor. This will have a partial poitive charge in general.

They can neutralize the charge and one gets the electrons it wants and the other gives the electrons it doesn't. Way simplified, but reactions are basically a nucleophile and an electrophile coming together. But some reactions are faster or compete or are to slow to notice so thats where all the confusing stuff comes in.

Learn to push electrons and know lewis dot structure very well. If you know whats happening with the electrons then you will know how the reaction is proceeding. There is a good book called Pushing Electrons (its orange i think).

Properties of molecules from general chemistry will be key in evaluating, and learn to know what is a good electrophile and a good nucleophile.

Ask Questions. So when I took O-chem i spent maybe 2 hours trying to figure out one thing. The next day someone asked and the 15 second response covered what took me that long to figure out. This is a class where the books are not always complete and trust me you need to ask questions.

A good TA or Tutor could be helpful if you are struggling. I will tell you that most people find this class difficult. Spend the time on understanding "why" not just the reactions which is the trap I see you falling into. Learn the stuff above. Hopefully you will learn everything I just talked about above and I know it may seem long, but just having gone through the process and taught it it would have been so much easier to just focus on the fundamentals.

As much as I dont want to tell you I found this book which at least in the edition I have has veryu good summaries ini table format of all the reactions.

Answer 2

a million) The numbers written above and below the arrows shows diverse reactions that used to rework the reagent(s) into the product(s) for chemical ameliorations that require more suitable than one step. In different words, the reagents listed below a million) are those that are mandatory to do the first step (reaction) interior the converstion, the reagents listed below 2) are those that are mandatory to do the second one step, etc. 2) i'm no longer precisely positive what you're asking the following yet i am going to attempt to respond to besides. at the starting up, the examples that you gave are not mechanisms, they're chemical equations. second, no longer all reactions are reversible. the celebration you gave is an celebration of a reaction that could no longer reversible, so the opposite equation that you gave would not truly make experience. Minus indications are not to any extent further typically used at the same time as writing chemical equations because reagents react with one yet another to grant one or extra products. the in effortless words celebration the position i'm able to imagine of utilizing a minus verify in a chemical reaction is in redox reactions, for instance, at the same time as electrons are exchanged. 3) straight forward salts will be utilized in IR. the classic platform used from the starting up of IR is potassium bromide (KBr) because of the toughness of the 'pellets' or plates that they type yet NaCl is likewise a usable salt. wish this helps!!!

Answer 3

http://www.cem.msu.edu/~reusch/VirtTxtJml/intro1.htm

This is a Virtual Textbook by William Reusch at Michiagn State University.
It has notes, problems, and animations.

Sometimes, after you click a link to a topic, who have to scroll down to find the topic.
