Structural Isomerism & Naming of Compounds EXPLAINED | Lecture 4 | IGCSE/O Level Chem (0620/5070)

Lecture 4 covers THREE crucial topics: cracking of alkanes, structural isomerism, and organic nomenclature (naming compounds). These topics are exam favorites and often appear in structured questions, so understanding them properly is essential. This lecture breaks down why cracking is important industrially, how to identify and draw isomers, and the step-by-step method for naming both straight-chain and branched organic compounds. 🔥 What you'll learn: • What is cracking? (Breaking large hydrocarbons into smaller ones) • Why cracking is endothermic (requires high temperature & pressure) • Catalysts used: Aluminum oxide & silicon dioxide • Products of cracking: Alkanes, alkenes, and hydrogen gas • Why cracking is industrially important (producing useful small-chain hydrocarbons) • What is structural isomerism? (Same molecular formula, different structure) • How to identify and draw isomers (e.g., butane vs 2-methylpropane) • Complete naming rules for alkanes and alkenes • Alkyl groups and their general formula (CnH2n+1) • How to name branched compounds (selecting longest chain, numbering rules) C• ommon exam mistakes in naming and how to avoid them Master these concepts and you'll handle any organic chemistry naming or isomerism question with confidence. 📌 Join the ChemFusion WhatsApp Community: https://chat.whatsapp.com/DMeJ4iHyxY7...
