(Options from previous syllabus)
*IMPORTANT INFORMATION*
The 'Options' are not part of the current 2023 syllabus (first assessment May 2025). They were an integral part of the old 2014 syllabus. I have retained them on this site for interest as teachers may wish to refer to them for ideas as to how the chemistry theory on the current syllabus can relate to practical and everyday uses in society. They may also stimulate ideas for students for both their Scientific Investigations (IA) and possible research questions for Extended Essays. They were originally written for teachers. I have not rewritten them to now address students, but I have put them in the student access section of this site, so that both teachers and students have full access. I have retained the links within the options but removed any of the links which refer to other parts of the 2014 syllabus (note also that some of the links to external sites may no longer be working). I have also retained the multiple choice quizzes and the short-answer questions together with all the worked answers. Remember they are for interest and, other than the relatively small amount of the content that has been incorporated into the 2023 syllabus, will not be examined.
