Joint Entrance Examination (JEE) is one of the most glorified examinations in our country conducted for admissions to various prestigious engineering colleges in India. Every student tries his/her level best to come up with the best results in this examination. Chemistry is one of the most scoring subjects to enhance one’s rank in JEE. According to the JEE syllabus, chemistry is widely branched into three categories: inorganic chemistry, organic chemistry and physical chemistry. Of all these categories, organic chemistry is a topic which requires thorough understanding of concepts to reach to the solution of a problem. General organic chemistry lays down the foundation for organic chemistry. Some FAQs related to general organic chemistry are underlined below:
Question: What are some of the important topics to cover in general organic chemistry?
Answer: According to JEE syllabus, general organic chemistry includes the concepts of
- Heterolyticand homolyticcleavage
- Stability of carbocation or carbanion
- Resonance effect, induction effect, nomenclature of compounds etc.
All the topics mentioned in this module are very important as they lay down the foundation for future chapters. For example resonance, stability of carbocation and carbanion etc. are very important to predict the product forvarious reactions in organic chemistry discussed in other chapters.
Questions: What approaches one can follow to solve the problems of general organic chemistry?
Answer: While solving the problems of general organic chemistry, for example arranging different ions on the basis of their stability.One should consider all the effects that can affect the stability of an ion such as resonance, induction, hyperconjugation etc.
Illustration: Why (CH3)3C+is more stable thanCH3+CH2 and+CH3?
Solution: (CH3)3C+has the maximum hyper conjugation interactionamong the three ions as the(CH3)3C+ionhas nine C-H bonds. Thus, it has the highest stability among the three ions. In +CH3,vacant p orbital is perpendicular to theplane in which C-H bonds lie; hencecannot overlap with it. Therefore,+CH3 lackshyper conjugative stability and has the least stability.
Questions: Which reference books can one follow for general organic chemistry?
Answer: While covering general organic chemistry for JEE, one must go through the NCERT class 11thchemistry textbook part-2. A brisk walk through this chapter from NCERT not only gives you a sound idea of the various topics you need to cover according to the JEE syllabus but also develops the fundamentals regarding the chapter. Apart from this you can follow a reference book to understand mechanisms of the reactions not given in the NCERT textbook. Some authentic books for understanding this topic includebooks from authors like Solomons and Fryhle, Morrisonand Boyd etc. Once you have developed concepts on this topic, you can practice questions from the books of authors like M.S. Chauhan, etc.
