Isomerism OCR AS Chemistry

Basic concepts of organic chemistry OCR AS Chemistry

This bundle is ideal for classroom or home learning and covers all of the OCR A level chemistry specification section 4.1.1 – basic concepts of organic chemistry, as well as isomerism from section 4.1.3 (Alkenes). The topics covered are: introduction to organic chemistry naming hydrocarbons quiz – a question of naming alkanes functional groups – names and formulae isomerism organic reagents and types of reaction Each topic includes a fully interactive PowerPoint including starter, group activities, questions and plenary along with a worksheet. Answers to all exercises are provided. Some of the resources include a PowerPoint quiz. This bundle is part of a series covering the OCR AS Chemistry specification and relates to the following sections: Module 4– Core organic chemistry Part 2 – Basic concepts and hydrocarbons 4.1.1 Basic concepts of organic chemistry (all) and 4.1.3 Alkenes (part) **Content covered:** **Introduction to organic chemistry** • Why carbon is special • Bonding in organic compounds • Different types of formulae • Types of organic compounds • Functional groups and homologous series **Naming hydrocarbons** • Application of IUPAC rules of nomenclature for systematically naming organic compounds • Naming alkanes and cycloalkanes • Naming branched alkanes • Naming alkenes and branched alkenes **Quiz – A Question of naming alkanes** **Functional groups – names and formulae** • Application of IUPAC rules of nomenclature for systematically naming organic compounds • Practice naming organic compounds including those with functional groups • Revision of empirical and molecular formula and how to calculate them • Formulae of compounds with functional groups - Displayed formula - Structural formula - Skeletal formula **Isomerism** • Shapes of alkanes (with model building) • Definitions of structural isomers, stereoisomers, E/Z isomers and cis-trans isomers • Classification of isomers with examples • Structural isomers including chain, position and functional group isomers • Shapes of alkenes (with model building) • Restricted rotation around the C=C double bond • Stereoisomers – E/Z and cis-trans isomers • Animated illustrations of E/Z isomers • Criteria for E/Z isomerism and for cis-trans isomerism with examples and learning check • Cahn-Ingold-Prelog rules for naming E/Z isomers with examples **Organic reagents and types of reaction** • Ways of breaking covalent bonds Homolytic fission Heterolytic fission • Types of organic reagents and their reactions - Nucleophiles - Electrophiles - Radicals • Introduction to mechanisms • Curly arrows • Types of reaction - Addition - Substitution - Elimination • Classification of reactions **Links** Next lesson: Topic 45 - Introduction to alkanes https://www.tes.com/teaching-resource/introduction-to-alkanes-ocr-as-chemistry-12654263
