Previously, i have shared a lot of key concepts regarding Organic Chemistry based on the GCE A-Level H2 Chemistry syllabus (code 9729) in Singapore, which is suitable for JC1 and JC2 A-Level students.
Today, i am going to do a consolidation of the key concepts for the following sub-topics in H2 Organic Chemistry:
- Introductory Topics (Types of Formulae, Isomerism)
- Alkanes
- Alkenes
- Arenes
For those in JC1 (J1), this few topics in Organic Chemistry will be tested in the upcoming Promotional Examination (Promos Exam).
You can click individual links below to learn more about each concept.
You can also watch some of my Chemistry YouTube Videos on Organic Chemistry which is consolidated at the end of this blog post.
Here we go ………..
