ORGANIC CHEMISTRY: the chemistry of carbon compounds

ORGANIC CHEMISTRY 

INTRODUCTION

One aspect is General Organic Chemistry. It deals with General Organic Chemistry i.e. basics organic chemistry.It starts with the concept of Hybridization, IUPAC Nomenclature, Isomerism, Resonance, Hyperconjugation, etc. Stereoisomerism is a critical part which becomes a bottleneck for most of the students. These concepts are used in almost every reaction mechanisms which are a part of topics like Hydrocarbons, Halides, Alcohols & Phenols, Aldehydes & Ketones, Carboxylic acids and derivatives and hence these are basics of organic chemistry. 
 Another aspect is Reaction part. This includes Hydrocarbons, Aromatic compounds, Alcohols, Phenols and Ethers, reactions of acids, Grignard Reagent, Oxidation/Reduction, etc. Revise it everytime before sitting to study. Understand the mechanism well. after studying the specific reactions named above, you should also be aware that they won’t be given to you in isolation. Instead, a lot of them are combined. Also, the reactants on which they must be carried out can be different from what you took when you learned them.

Thus it is probable that you would get baffled seeing such a large number of unknown problems at one place. The key to overcome this problem is to know the mechanism of each reaction.

So you must first know the intermediate species (if any) involved in the reaction. So you must search for the possible electrophilic centers in the molecules or any nucleophilic reagent. Once you find these two things, it’s almost done.

Now as you know a nucleophile attacks an electrophile, you just need to know how the electrons will move in the molecule. Make the necessary electron displacements and you are done. But this is something that may not strike you immediately when you see the question. You should practise a lot.

PRACTISE

Organic Chemistry is best mastered by solving problems that involve multiple concepts at the same time. You must figure out the best approach to attack each problem. As you can see, mastering this subject is a slow and steady process.

There will be problems in the beginning due to a lot of hidden concepts from the above mentioned two topics. But as mentioned above, it is essential to have a stronghold on them. 

Don’t try to rush through topics just for the sake of completing the syllabus. Be patient, try to make your basics strong by solving a lot of problems. Once you can do that well, you will find the rest of the portion extremely easy and small to wrap up.

Topic wise weightage for organic  chemistry IIT JEE:





Organic chemistry has at least 30-40% weight-age in the IIT JEE chemistry paper. It is the most critical part of chemistry where scoring is important to occupy a high berth in AIR of IIT JEE.
