Organic Chemistry JEE

There is no entering into organic chemistry without knowing the General Organic Chemistry and that’s a fact. The basic mechanisms and reactions follow up in every chapter but that requires you to know some fundamental reasoning. Unlike inorganic chemistry, here the reaction mechanisms have a pattern. The quantity might get overwhelming over time but is nonetheless useful in the long run. Naming reactions are the crown jewels of Organic Chemistry. Over the past 10 years, 112 questions have been asked from this unit. Some of the important chapters from this unit are: Amino Acids & Polymers, GOC, POC, Hydrocarbons, Alkyl Halides and Aromatic Compounds. Environmental chemistry might turn out to be an easy scoring chapter but owing to its low weightage, it should be prepared at the end.

Q. is organic chemistry difficult for JEE?

No, organic chemistry is not difficult. All reactions are interrelated so it is advised that you follow the proper sequence of the chapter. One area where most students lack is that they do not focus much on nomenclature, remember nomenclature is the ABCD of organic chemistry if it is not clear to you, you will not be able to cope up with OC.

Q. Is organic chemistry important for JEE?

Every year about 11 to 15 questions for 44 to 60 marks are asked in JEE so it is one of the most important topics for JEE. Topics like aldehyde ketone and after that are all important for 12th board exams also. So you will have to study the topic in-depth to score well in boards and JEE.

Q. Is NCERT enough for organic chemistry for JEE?

Not for getting a Rank below 10000. JEE will ask 30% of questions that will be from NCERT but for the remaining 70%, NCERT will be of no use. Again the weightage of hydrocarbons in boards is less as compared to that of JEE. So will not advise you to be only dependent on NCERT.

Q. How to prepare for organic chemistry?

You cannot skip topics in organic chemistry you will have to follow the complete sequence of topics BOC followed by nomenclature and so on so forth. All the topics have interdependency so skipping any topic will result in you not understanding the next topic. This is the only method to score well in OC

Q. How can I improve my organic chemistry?

Organic chemistry is tricky since you have to imagine reactions happening from all dimensions. This can be difficult to understand unless your class teachers are using 3D figures to explain the reactions. At Kaysons we have used 3D animation to help you clear and understand complex reactions which will help you in scoring well in organic chemistry.

Q. Best books for organic chemistry for JEE?

People do recommend books like Morrison and bolyd, other international books but we will not recommend them, the reason is that they contain a lot of information that is not needed for JEE. We will advise you to go for OP Tandon or Arihant now remember both these books have over 2500 pages and will be very difficult for you to read and understand plus costing of over Rs 2500 will not be much use. So rather than books, we will advise you to use some video lectures to master Organic Chemistry.

Q. How many questions are asked from organic chemistry?

Every year about 11 to 15 questions for 44 to 60 marks are asked in JEE, of which 6.33% asked from GOC while hydrocarbons 6.5%, amines 3.6% biomolecules and polymers 5.8% while alcohols, phenols, ether etc 8.5%.
