Organic Chemistry:
Is a subdiscipline of chemistry that studies the structure, properties and reactions of organic compounds, which contain carbonin covalent bonding. Study of structure determines their chemical compostionand formula. Study of properties includes physicaland chemical properties, and evaluation of chemical reactivity to understand their behavior. The study of organic reactions includes the chemical synthesisof natural products, drugs and polymers, and study of individual organic molecules in the laboratory and via theoretical (in silico)study.
Includes
• Introduction to Organic
• Isomersim and Reaction
• Hydrocarbon
• Halogen compound
• Alcohol Phenol ether
• Ketones and Aldehydes
• Carboxylic Acid and Derivatives
• Nitrogen Compounds
• Biomolecules
• Polymers in Everyday in life
Analysis:
Organic Chemistry is quite balanced i.e., it contains 14-20 questions on average and constitutes one-third of the questions, much like its share on the syllabus. The number of questions fluctuate every year but it is estimated that at least 15 questions will be asked from this segment in the upcoming year, 2020. The very basics of O-Chem lies with the reaction mechanisms and these are further used in later chapters to understand scores of important named reactions. The end chapters such as biomolecules and polymers in everyday life take up very less time but end up appearing in the exam and thus must be taken care of.
How to prepare:
While mugging up is true for Inorganic Chemistry, Organic fortunately can be built up with concepts and need not be worried. Chemical Bonding is very significant and learning theories will help you stay clear in the mess. Atomic and Chemical Properties, IUPAC Nomenclature etc. will help study the later chapters easily. Mindmaps and Flash Cards are extremely handy in such situations and help categorise reactions and elements to connect further links. Mechanisms will act as the ultimate decider between acing or failing your exams because it is beyond superficial understanding. Understanding individual steps of the reaction will eliminate errors in any modifications in the question. Make a notebook and revise to stay in touch and refer to understanding mostly and not memorization. Memorize and your efforts will most likely go in vain.

Chapter: Isomerism And Reaction
Introduction:
Isomerism, the existence of molecules that have the same numbers of the same kinds of atoms (and hence the same formula) but differ in chemical and physical properties. The roots of the word isomer are Greek—isos plus meros, or “equal parts.” It has two types - structure and stereo isomerism both of them are described in detail . Importance of coordination compounds (in qualitative inclusion, extraction of metals and biological system) is also included .
Chapter Analysis:
There have been lot of irregularities in providing questions from this chapter . There have been short intervals with continuous questions and then another gap of years where there have been no questions posed . A total of 10 questions have been asked in the previous 11years which indicates it is a low weightage chapter . We can nevertheless expect 1 or 2 questions from this .

Chapter: Carboxylic Acid and Derivatives
Introduction:
A carboxylic acid is an organic compound that contains a carboxyl group (C(=O)OH). The general formula of a carboxylic acid is R–COOH, with R referring to alkyl group of the (possibly quite large)molecule. Carboxylic acids occur widely. Important examples include the amino acids(which make up proteins) and acetic acid (which is part of vinegar). Deprotonation of a carboxyl group gives a carboxylate anion. Important carboxylate salts are soaps which are formed by their derivatives only .

Q. How to Study Organic Chemistry For NEET??
Organic chemistry is often deemed complicated by students, but if studied properly students can easily score a lot of in it.
- Clear your foundation – Focus on clearing your basics with the 11th and 12th class NCERT books. Go line-by-line and understand each concept thoroughly. NCERT books are the foundation for NEET exams.
- Thoroughly understand the concepts – Organic chemistry is entirely concept based. Therefore it is very important for you to thoroughly understand every concept and all the mechanisms of the reactions.
- Practice questions – After you understand the mechanisms of the reactions, try to write it down on your own. Practice a few reactions everyday to tighten your grip. Then try to solve questions including the previous year’s question papers. The more questions you solve, the more confident and experience you gain.
- Put more efforts on select chapters – After you practice a lot of questions you get a pretty good idea of which subjects need more preparation. After the tests go through those topics thoroughly and solve more questions related to it.
- Follow reference books – Following the NCERT builds your foundation but they are not enough to score well in the organic chemistry. After you are done with the NCERT, follow other good reference books and study materials.
