AS-Level Chemistry revision

What's on AS-Level Chemistry

Coverage is roughly the first year of A-Level Chemistry:

• Atomic structure, bonding and amount of substance (mole calculations).
• Energetics and kinetics — including enthalpy changes and rates of reaction.
• Equilibria — Le Chatelier's principle and Kc.
• Periodic table and inorganic trends (Group 2, halogens).
• Organic chemistry: alkanes, alkenes, halogenoalkanes, alcohols. Mechanism drawing.
• 6 required practicals at AS — full apparatus + technique recall.

How to revise AS-Level Chemistry

Drill mole calculations to muscle memory. Memorise organic reaction maps (alkane → halogenoalkane → alcohol). Practise the 'explain why' synthesis questions linking bonding to physical properties. Required-practical apparatus + variable control is examinable on every paper.

Frequently asked

Is AS Chemistry easier than A-Level Chemistry?

AS covers the first-year content only — the second-year additions (transition metals, advanced organic mechanisms, NMR/MS spectroscopy on some boards) are not examined at AS.

Do I need A-Level Maths to do AS Chemistry?

Not formally required but highly helpful. Around 20% of marks involve quantitative work overlapping with Higher GCSE Maths. A-Level Maths concurrent study makes the energetics and kinetics maths easier.
