This "all-in-one" resource is the definitive guide for students aiming for top marks in the NCEA Level 2 Chemistry external exams. By combining the three core external standards into one volume, it ensures students can master the essential theories of structure, energy, and reactivity in a cohesive way.
Key Features
Triple Standard Coverage: Comprehensive notes and practice for all three external NCEA Achievement Standards:
AS 91164 (2.4): Bonding, Structure, Properties, and Energy.
AS 91165 (2.5): Organic Chemistry (Structure, properties, and reactions).
AS 91166 (2.6): Chemical Reactivity (Rates of reaction and equilibrium).
Deep Structural Analysis: Detailed guides on Lewis structures, molecular shapes, and the polarity of molecules, linking these to physical properties like melting points and solubility.
Organic Chemistry Pathways: Clear, step-by-step maps for identifying organic functional groups (alkanes, alkenes, alcohols, haloalkanes, and carboxylic acids) and predicting their reaction products.
Reactivity & Equilibrium: In-depth explanations of Collision Theory and Le Chatelier’s Principle, providing the vocabulary and logic required to explain changes in chemical systems.
Thermochemistry Mastery: Includes extensive practice in calculating enthalpy changes ($\Delta H$) and understanding the energy shifts in chemical bonds.
Exam-Focused Practice: Features a vast array of NCEA-style questions, from "identify and describe" tasks to the complex "compare and contrast" essays required for Merit and Excellence.
