This complete year 12 lesson on introduction to alkanes covers part of OCR sections 4.1.2 (Alkanes). Content covered includes uses of alkanes as fuels, bonding and shapes of alkanes and their physical properties. The resource features a 27 slide animated PowerPoint along with a 6 page workbook. There is a starter activity and a short quiz as a plenary. Exam tips and answers to the exercise are provided. Ideal for the classroom or blended learning, this resource could be used as an introduction to the topic, or for revision, extension or consolidation. This lesson is part of a series covering the OCR AS Chemistry specification and relates to the following part of the specification: Module 4 – Core organic chemistry Part 1 – Basic concepts and hydrocarbons 4.1.2 − Alkanes Content covered: Sources and uses of alkanes Definitions of fossil fuels and crude oil Uses of alkanes as fuels Bonding in alkanes Formation and rotation of sigma bonds Shapes of alkanes Intermolecular forces in alkanes in terms of non-polar molecules Melting and boiling points of alkanes in terms of London forces Effect of chain length and branching on London forces Duration: 1 lesson If you find this free resource useful, please leave a review!

Identifying compounds from infrared and mass spectra (A level)

(7)
A set of five problems to practise identifying organic compounds from % composition, infrared (IR) spectroscopy and mass spectrometry. Suitable for AS or A2 level, this type of exercise is good preparation for exam questions on identifying organic compounds using combined spectroscopic techniques. It could also be used for revision or consolidation of IR spectroscopy and mass spectrometry, as well as for assessment for learning. Full answers to all the problems are provided. This resource was developed primarily for the OCR A level Chemistry specification but is useful for all specifications. It relates to the following sections : AS: Module 4 – Core organic chemistry Part 2 – Alcohols, haloalkanes and analysis 4.2.4 Analytical techniques A2: Module 6 – Organic chemistry and analysis Part 3 – Analysis 6.3.2 Spectroscopy (Combined techniques) Please review! Content covered • Calculating empirical formula from % composition • Calculating molecular formula from empirical formula and molar mass, using the molecular ion peak on the mass spectrum • Using the infrared (IR) spectrum to identify bond stretches and hence functional group(s) present • Drawing structural formulae consistent with the molecular formula and IR data • Using mass spectrum to distinguish between the suggested structural formulae • Identifying fragments in the mass spectrum Duration: 1 part lesson and/or independent study Links Please see also: infrared (IR) spectroscopy - A level https://www.tes.com/teaching-resource/infrared-ir-spectroscopy-a-level-home-learning-self-study-12315096 mass-spectrometry - A level https://www.tes.com/teaching-resource/mass-spectrometry-a-level-home-learning-self-study-12287938 mass spectrometry summary AS home learning https://www.tes.com/teaching-resource/mass-spectrometry-summary-as-home-learning-coronavirus-12287495
