Qualitative Analysis of Organic Functional Groups

Analysis (OCR)

5 Full Lesson Bundle on Analysis from the OCR A Level Chemistry specification. Please review the learning objectives below. Lesson 1: Chromatography 1. To interpret one-way TLC chromatograms in terms of Rf values 2. To interpret gas chromatograms in terms of: (i) retention times (ii) the amounts and proportions of the components in a mixture 3. To understand the creation and use of external calibration curves to confirm concentrations of components. Lesson 2: Qualitative Analysis of Organic Functional Groups 1. To recall qualitative analysis of organic functional groups on a test-tube scale 2. To design qualitative analysis tests to distinguish between two or more organic compounds Lesson 3: Carbon-13 NMR Spectroscopy To analyse a carbon-13 NMR spectrum of an organic molecule to make predictions about: 1. The number of carbon environments in the molecule 2. The different types of carbon environment present from chemical shift values 3. Possible structures for the molecule Lesson 4: Proton NMR Spectroscopy (Part 1) To analyse proton NMR spectra of an organic molecule to make predictions about: 1. The number of proton environments in the molecule 2. The different types of proton environment present from chemical shift values Lesson 5: Proton NMR Spectroscopy (Part 2) (includes combined techniques) To analyse proton NMR spectra of an organic molecule to make predictions about: 1. The different types of proton environment present from chemical shift values 2. The relative numbers of each type of proton present from the relative peak areas using integration traces or ratio numbers when required 3. The number of non-equivalent protons adjacent to a given proton from the spin-spin splitting pattern, using the n+1 rule 4. Possible structures for the molecule Note: 2 Exam Questions on Combined Techniques are also included in lesson 5! ***Declaimer: Please refrain from purchasing this popular resource for an interview lesson or a formal observation. This is because planning your own lessons including using your own lesson PowerPoints is a fundamental skill of a qualified/unqualified teacher that will be reviewed during these scenarios outlined above***
