Overview

Hydrocarbons are organic compounds containing only carbon and hydrogen atoms. They form the foundation of organic chemistry and are essential components of fuels, plastics, and many industrial chemicals. This chapter explores the structure, properties, preparation, and reactions of different types o

Key Concepts

Hydrocarbons are classified based on structure

Hydrocarbons are classified based on structure: Open chain (aliphatic) include saturated alkanes (CnH2n+2) and unsaturated alkenes (CnH2n) and alkynes

Compounds with same molecular formula but

Compounds with same molecular formula but different structural arrangements. Chain isomerism occurs when carbon skeleton differs (n-butane vs isobutan

Different spatial arrangements of atoms due

Different spatial arrangements of atoms due to rotation about C-C single bonds. In ethane, staggered conformation (lower energy) and eclipsed conforma

Occurs due to restricted rotation about

Occurs due to restricted rotation about C=C double bonds. Cis-isomers have similar groups on same side of double bond, trans-isomers have them on oppo

Alkane halogenation proceeds through initiation (Cl₂

Alkane halogenation proceeds through initiation (Cl₂ → 2Cl•), propagation (CH₄ + Cl• → CH₃• + HCl; CH₃• + Cl₂ → CH₃Cl + Cl•), and termination steps. R
