High-resolution mass spectrometry A level Chemistry? Calculating the accurate relative molecular mass of a compound using accurate relative atomic masses to four decimal places? All this and more covered in this comprehensive lesson with questions and answers! This is a Year 13 A level lesson for Edexcel International Unit 4 – WCH14, but it can also be used for all UK exam boards. All the slides in this lesson are fully animated and include answers to every mini plenary question and exam question. The breakdown of the slides (which are best opened on Microsoft PowerPoint) is as follows:

Slide 1 - Title and 5-minute starter. The starter is a grid of four questions entitled ‘last week, last lesson, today’s learning and future learning’. Use this generic slide for all your lessons by simply changing the questions and the answers each time.
Slide 2 - Lesson objectives (see thumbnail image)
Slide 3 – use this slide as recap quiz on mass spectrometry
Slide 4 – introduction to what high-resolution mass spectrometry is
Slides 5 – 6: print these slides for the students. They are copies of high resolution mass spectra to glue in their books
Slide 7 – use this slide to explain the usefulness of accurate relative molecular masses
Slides 8 – 10: this section provides students with data to calculate the accurate relative molecular mass Print slides 9 and 10 so that students have copies of the data
Slides 11 – 13: Worked example 1 - Use this section to model to students how to deduce the structure of a compound using accurate relative atomic masses. Print slides 12 – 13 for the students, so they can have a copy of the question
Slides 14 – 17: Worked example 2 - Use this section to model to students how to deduce the structure of a compound using accurate relative atomic masses. Print slides 15 - 16 for the students, so they can have a copy of the question
Slides 18 – 20: exam questions with mark scheme answers included with this resource

Edexcel International A level Chemistry - lessons with questions and answers | Topic 15 | Organic Chemistry: Carbonyls, Carboxylic Acids and Chirality

Bundle is comprised of 13 PowerPoint lessons covering Topic 15 – Organic Chemistry Carbonyls, Carboxylic Acids and Chirality for the Edexcel International A level Chemistry course, Unit 4 – WCH14, but it can be used for all UK exam boards which have an Organic Chemistry unit. The PowerPoints are as follows: 1. Optical isomerism 2. Optical activity and reaction mechanisms 3. Carbonyl compounds 4. Nucleophilic addition 5. Carboxylic acids 6. Acyl chlorides 7. Esters 8. Polyesters 9. Simple chromatography 10. Determining structures using mass spectra 11. High performance liquid chromatography, gas chromatography and gas chromatography mass spectrometry 12. Carbon NMR spectroscopy 13. Proton NMR spectroscopy Each lesson is exactly that . . . a lesson. There is a starter slide, lesson objectives slide, introduction of new knowledge slides, worked examples and then opportunities for students to try independent practice through mini plenary tasks comprised of several questions of graded difficulties. Questions are interspersed through the lessons at regular intervals and always have answers that animate on to the screen when you click. THESE ARE NOT THE INFORMATION ONLY TYPE SLIDES THAT SOME PEOPLE SELL, which are useless for delivering a lesson. We are a team of teachers, and these lessons have been made by actual Chemistry teachers who currently teach in secondary schools in England. We know exactly what you need, trust us. Every lesson has exam questions included as word documents which were made using Exam wizard. The mark scheme is at the end of each exam question and the answers have been screen shotted and pasted into the PowerPoint at the end. All the slides in every lesson are fully animated and include answers to every mini plenary question and exam question. Please note: core practicals have not been included, as we are preparing a separate resource for all the core practicals. Watch this space! Please consider leaving a review! It really helps promote our store! Thank you!
