Chemistry

Summary

Chemistry is one of the primary choices of those looking to embark on a STEM field. The subject sees one of the biggest jumps from IGCSE level to A Level in terms of the complexity of the material covered. Yet, it’s nothing to be fearful of for those intellectually curious and willing to put in the necessary hard work.

 

The speciation is meant to be covered in 6 units. Units 1, 2 & 3 are meant to be done in AS, whereas, units 4, 5 & 6/7 are meant to be done in A2. Unit 6 serves as the written alternative to Unit 7 which is a practical exam. It’s highly encouraged that students opt for unit 7 instead of unit 6 to get a hands on experience of working in labs.

 

The course starts with unit 1 which covers the fundamentals of chemistry from atomic structures to energetics and basic laws of formulae writing and is probably the easiest unit to ace.  Alkanes and alkenes are covered in the organic chemistry as well. Unit 2 covers molecular structures, inter and intra molecular bonding and periodic trends. It also covers alcohols and halogenoalkanes. Unit 4 introduces thermodynamics, equilibria, acids and bases as well as carbonyl compounds and carboxylic acids. Chemistry of aromatic compounds and transitions metals are dealt with in unit 5 and it remains as the most dreaded of all units.

 

Although all the information may seem overwhelming at first, with the necessary effort and repeated revision, the subject can be conquered. The recommended books for chemistry are the student books and George Facer books paired with the past papers.
