Trusted teacher: 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.

£16LEARN ZAMBIAN LANGUAGES LIKE: BEMBA, NYANJA, MAMBWE AND TONGA WITH YOUR BEST TUTOR.
Trusted teacher: Zambian languages remains so important to any VISITOR and any INDIGENOUS Zambian who wishes to improve in communication skills.To give you the picture, once you know BEMBA language, you can easily be understood by anyone in all 10 provinces of the country.On the other hand , NYANJA gives an advantage to be understood especially in LUSAKA-Zambia's capital city and also in other provinces.Other, languages like TONGA and MAMBWE are provincial based; TONGA is the WIDELY spoken language in SOUTHERN province and MAMBWE in MUCHINGA province.Why LEARN Zambian languages? It saves you from language barrier and many inconveniences that comes with expressing your thoughts or ideas . New words are always taught per class session , correct spellings and pronunciation of words are emphasized. Prior to notifying me that you won't be available for a class, a class video is recorded and sent to you.If you are available then an ONLINE class takes place. On the other hand, students loves the fact that we do have customized time tables. We make a time table for a student depending on their convenient day/s and time .This flexibility in time and time table makes it very much accommodating to learners who are either very busy in the morning or afternoon. It is always motivating, satisfying and inspiring to meet the demands of each student.

£35Ingénieur, économiste et doctorant donne cours de Maths / Économie (Micro / Macro et Économétrie) niveau secondaire et universitaire
Trusted teacher: Ingénieur de formation et doctorant en sciences économiques, je désire partager mes connaissances acquises au cours de mes études avec des étudiants de tout âge dans le Brabant-Wallon et au-delà. Mon objectif est d’aider mes élèves à aborder les mathématiques et les sciences économiques (Microéconomie / Macroéconomie et économétrie) sous un angle différent pour gagner en confiance et améliorer leurs résultats scolaires. A cet effet, je construis des explications ciblées sur base des besoins réels. Aussi, j’aide mes étudiants à atteindre leurs objectifs, en réussissant un concours, un examen, ou un test (GRE quantitative section). Mes cours s’adressent aux élèves du secondaires et aux étudiants en bachelier. Mon objectif est d’aider vos enfants à mieux comprendre les notions de cours d’une part, et d’améliorer leurs résultats scolaires d’autre part. Je mets en place des méthodes d’apprentissage innovantes pour rendre agréable le parcours d’apprentissage. Cela passe par une adaptation aux besoins de l’étudiant, à travers des exercices concrets et des exemples clairs. Aussi, je veille toujours à garder un bon équilibre entre la théorie et les exercices et à faire participer l’élève au maximum pour garantir que les notions enseignées soient bien assimilées.
