In the IGCSE and CIE (AS/A Level) Biology and Chemistry curricula, Organic Chemistry is a major topic, particularly within Chemistry. Here's a breakdown of what is covered at each level: --- IGCSE Chemistry (Cambridge - 0620/0971) In IGCSE, Organic Chemistry focuses on the fundamentals of carbon compounds and their reactions. Key areas include: 1. Introduction to Organic Chemistry - Definition: Organic chemistry is the study of carbon-based compounds. - Hydrocarbons: Compounds made up of carbon and hydrogen only. 2. Types of Hydrocarbons - Alkanes: - General formula: CnH2n+2 - Properties: Saturated hydrocarbons (single bonds). - Combustion and substitution reactions. - Alkenes: - General formula: CnH2n - Properties: Unsaturated hydrocarbons (double bonds). - Addition reactions (e.g., with bromine water as a test for alkenes). 3. Functional Groups and Homologous Series - Alcohols: General formula CnH2n+1OH (e.g., ethanol). - Properties and combustion. - Carboxylic Acids: General formula CnH2n+1COOH(e.g., ethanoic acid). - Weak acids, their reactions, and uses. 4. Polymers - Addition Polymerization: Formation of polymers from alkenes (e.g., poly(ethene), poly(propene)). - Natural and Synthetic Polymers: Proteins, nylon, and plastics. - Environmental Issues: Problems with non-biodegradable plastics. --- CIE AS and A Level Chemistry (9701) At the AS/A Level, Organic Chemistry is studied in greater depth, with emphasis on structure, reactions, and mechanisms. Key topics include: 1. Structure and Bonding in Organic Compounds - Structural, displayed, and skeletal formulas. - somerism: - Structural isomers. - Stereoisomerism: cis-trans(E/Z) isomerism. 2. Functional Groups and Reactions - Alkanes: Combustion and free radical substitution reactions. - Alkenes: Addition reactions (e.g., hydrogenation, halogenation, hydration). - Alcohols: Preparation (hydration of ethene) and oxidation (to aldehydes, ketones, or carboxylic acids). - Halogenoalkanes: Nucleophilic substitution reactions. - Carboxylic Acids: Reactions (e.g., neutralization, esterification). - Esters: Formation and hydrolysis. 3. Mechanisms of Reactions - Free radical substitution (e.g., in alkanes). - Electrophilic addition (e.g., in alkenes). - Nucleophilic substitution (e.g., in halogenoalkanes). 4. Polymers and Biochemistry - Addition and condensation polymers. - Structure of proteins and DNA. 5. Organic Synthesis - Pathways for converting one functional group to another. - Use of reagents, conditions, and mechanisms in synthesis. Summary - IGCSE Organic Chemistry focuses on basic hydrocarbons (alkanes, alkenes), functional groups (alcohols, carboxylic acids), and polymers. - AS/A Level Organic Chemistry goes deeper into mechanisms, isomerism, synthesis pathways, and advanced functional groups.

Eliot - Nantes, France£25
£25Private lessons in Mathematics and Physics-Chemistry - All levels
A final year student at an engineering school (École Centrale de Nantes) with three years of experience in private lessons, I offer personalized support in mathematics and physics for all levels: middle school, high school, and higher education. 🎯 My Methodology My approach is based on three pillars: 1. 📋 Initial assessment: During the first session (free), we identify the student's strengths and weaknesses in order to develop a program adapted to their objectives (rapid progress, preparation for exams, consolidation of the basics). 2. 🧠 Interactive pedagogy: - 📚 Clear and illustrated explanations for a thorough understanding. - ✏️ Progressive exercises to consolidate acquired skills. - 🎓 Exam simulations and solving typical topics to build confidence and prepare effectively for the tests. 3. 📈 Regular and personalized monitoring: - 🗂️ Summary sheets of the concepts studied. - 📝 Targeted training exercises to perform between classes. - 🔄 Accurate feedback on progress with adjustments if necessary. ⭐ My experience - 3 years of experience in private lessons. - Organization of intensive courses to prepare for exams and competitions (baccalaureate, preparatory classes for grandes écoles). - Personalized support for stress management and test methodology. 📍 Courses available online or in Nantes. 👉 Book your first free session now and put all the chances on your side to succeed in your exams and competitions!
