Alkenes and alkynes are important classes of organic compounds studied in chemistry. Here are some key concepts related to alkenes and alkynes that you may come across in a JEE (Main+Advanced) integrated course:

1. Structure and bonding: Alkenes and alkynes are unsaturated hydrocarbons that contain carbon-carbon double and triple bonds, respectively. The double and triple bonds result from the overlap of p orbitals on adjacent carbon atoms, forming a pi bond.
2. Nomenclature: Alkenes and alkynes are named using the same rules as alkanes, but with the suffix -ene or -yne, respectively, replacing -ane. The position of the double or triple bond is indicated by a numerical prefix before the -ene or -yne suffix.
3. Reactions: Alkenes and alkynes undergo a variety of reactions, including addition reactions, elimination reactions, and oxidation reactions. Addition reactions involve the addition of a molecule across the double or triple bond, while elimination reactions involve the removal of a molecule to form a double or triple bond. Oxidation reactions involve the addition of oxygen or removal of hydrogen from the molecule.
4. Stereochemistry: Alkenes and alkynes can exhibit geometric isomerism, in which the atoms or groups attached to the double or triple bond are arranged differently in space. This can lead to different physical and chemical properties for the isomers.
5. Synthetic applications: Alkenes and alkynes are important building blocks in organic synthesis, and are used in the production of a wide range of industrial and consumer products, including plastics, polymers, and pharmaceuticals.
