Alcohols, haloalkanes and analysis bundle OCR AS Chemistry

This bundle covers all of the OCR A level chemistry specifications section 4.2 (alcohols, haloalkanes and analysis)

The resources included are:

• chemistry of alcohols
• haloalkanes
• organic synthesis
• AS synthetic routes
• infrared spectroscopy
• mass spectrometry
• identifying compounds from infrared and mass spectra

Most of the resources include a fully interactive PowerPoint including starter, group activities, questions and plenary along with a worksheet. Many of the PowerPoint slides contain links to other slides, to enable easy navigation and to emphasise links between different aspects. Some of the resources include a PowerPoint quiz and all are ideal for classroom or home learning.
The synthetic routes resource covers AS organic synthetic routes through a 15 slide interactive PowerPoint that is based on a clear chart of numbered synthetic routes, where each number is linked to a page detailing that reaction. Information given includes type of reaction, reagents and conditions and an equation, as well as key definitions. In addition most reactions have an animated mechanism or structural equation. There are links to pages describing and explaining practical techniques, where relevant.
Also included is a resource consisting of a set of five problems to practise identifying organic compounds from % composition, infrared (IR) spectroscopy and mass spectrometry.
Full answers to all exercises are provided.

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 –Alcohols, haloalkanes and analysis (all)
