How to deal with Organic Reactions

How to learn the reactions of Organic Chemistry?
When one starts the Organic Chemistry in Second year, the first chapter that is the introduction is usually quiet easy to understand. The concepts are familiar to the one's we started reading about in the Organic Chemistry chapter from matric text book. How ever once the next chapters start, the concepts become too much to comprehend. Yes the physical properties, uses and structures are comprehensible but the chemical reactions are a bit too much.
With each successive chapter, the no of chemical reactions increases and it becomes confusing to remember what reacts with what to give you what. The alkanes, alkenes and alkynes all end up reacting with the same chemicals yet give varying products. here are some tips to make you understand the reactions in a better light:
Keep a pencil and paper with you while studying reactions. The more you right things down, the more they stay with you for ever.
Understand what is going on the reaction. This may seem tiresome but it is better to know where the electrons are going, how the bonds are being made and reformed again. So that if you forget the real equation, you can come up with it on your own using the chemical techniques which actually make the reaction happen.
This is also helpful in the Entry Test examination where the reactions may not be exactly like the ones given in the book. So if you know the mechanism of action, the organic chemistry multiple choice questions would be a piece of cake.
Make it visual. the more you make the reactions elaborate and colorful, the better. This is specially good when you are beginning Organic Chemistry. Once you get a hang of this, you wont be needing too much illustrations.
Also do lots and lots of practice on paper. The more you do that, the more it will stick in your brain. It is kind of like Mathematics in that way. Practice is the key.
