Organic Chemistry JEE Notes

Organic chemistry notes for JEE, provided here, will help students with effective preparation and score better in this section. Organic chemistry notes cover almost all the fundamental concepts discussed in the latest JEE syllabus, including important topics that usually have a high weightage, as seen from previous question papers. We, at BYJU’S, are offering important JEE notes that have been prepared by our top subject experts for the upcoming JEE Main and JEE Advanced exams. Referring to these organic chemistry notes will help candidates to develop a strong conceptual base, along with the knowledge of its practical applications. These notes will boost students’ last-minute preparation significantly and ultimately help them achieve better scores in this section.

Introduction to Organic Chemistry

Topics Covered in JEE Organic Chemistry Notes

Organic chemistry JEE notes will help to get a brief overview of all the topics. In this section, we have provided the organic chemistry notes PDFs so that students can use them for the preparation of the main exam.

Organic Chemistry Important Points

Organic chemistry is the branch of chemistry that involves the scientific study of organic compounds. It is a vast science due to one key property exhibited by the element carbon (also called carbon catenation). Catenation is the ability of an element to form bonds with an atom of the same kind. Hence, the vastness of organic chemistry can be attributed to this property of carbon.

Let us discuss a few important definitions of organic chemistry.

1. Bonds can cleave in either of two ways: homolytic cleavage and heterolytic cleavage.
2. Carbenes are neutral and reactive species that have six electrons in the outer shell of carbon, making them electron deficient. Carbenes can be classified based on their spin states.
3. Triplet carbene is more stable than a singlet.
4. Carbocations and carbanions

Carbocations have a sextet of electrons on the carbon-containing positive charge and are hence termed the ‘cation’.

Carbanions are generated by heterolytically cleaving a group attached to carbon without removing the bonded electrons. 

5. Electrophiles and nucleophiles

Electrophiles are electron-deficient organic reagents. It can be generalised that all the positive charge-containing species.

Nucleophiles are electron-rich organic reagents.

6. Resonance effect: The polarity induced in a molecule by the interaction of a lone electron pair with a pi bond or the interaction of two pi bonds in nearby atoms is known as the resonance effect.
7. Mesomeric effect: The mesomeric effect is the polarity that develops in a molecule as a result of interaction between two -bonds or a -bond and a lone pair of electrons.
8. IUPAC rules: The nomenclature of organic compounds follows the recommendations of the IUPAC in naming organic compounds, carbocations, etc. The International Union of Pure and Applied Chemistry (IUPAC) formulates rules for naming organic compounds.
9. When two atoms share one or more than one pair of electrons that hold them together in a chemical bond is defined as a covalent bond. 
10. Inductive effect: Inductive effect refers to the phenomenon wherein a permanent dipole arises in a given molecule due to the unequal sharing of the bonding electrons in the molecule. This effect can arise in sigma bonds, whereas the electromeric effect can only arise in pi bonds.
