📚 AQA A-Level Chemistry: Specification at a Glance | AQA A-Level 化学：考试大纲概览

Welcome to this concise overview of the AQA A-Level Chemistry specification. This guide is designed to help students, parents and teachers quickly understand the structure, content and assessment of the AQA Chemistry A-level (7405), so that revision and preparation can be focused and effective.

欢迎阅读本份针对 AQA A-Level 化学考试大纲的概览。本指南旨在帮助学生、家长和教师快速理解 AQA 化学 A-Level（科目代码 7405）的结构、内容与评估方式，使复习与备考更有针对性、更高效。

1. Subject Content Overview | 内容总览

The AQA A-level Chemistry specification is divided into three broad areas: physical chemistry, inorganic chemistry and organic chemistry. These areas are not taught as isolated blocks; instead, they are interlinked through overarching concepts such as bonding, energetics and the behaviour of chemical species.

AQA A-Level 化学大纲分为三大领域：物理化学、无机化学和有机化学。这些领域并非孤立教学，而是通过化学键、能量学及化学物种行为等核心概念相互关联。

Physical chemistry covers the quantitative and theoretical foundations: atomic structure, amount of substance, bonding, energetics, kinetics, equilibria and redox processes. Inorganic chemistry explores the periodic table, groups 2 and 7, period 3 elements and transition metals. Organic chemistry includes the chemistry of alkanes, alkenes, alcohols, aromatic compounds, polymers, amino acids and many functional-group transformations.

物理化学涵盖定量与理论基础：原子结构、物质的量、化学键、能量学、动力学、平衡与氧化还原过程。无机化学探讨元素周期表、第2族与第7族、第3周期元素及过渡金属。有机化学涵盖烷烃、烯烃、醇、芳香族化合物、聚合物、氨基酸及多种官能团转化。

2. Paper 1: Physical and Inorganic Chemistry | 试卷一：物理化学与无机化学

Paper 1 is a two-hour written examination worth 105 marks, constituting 35% of the A-level. It focuses on relevant sections of physical chemistry (1.1–1.7) and all inorganic chemistry (2.1–2.6), together with the associated practical skills.

试卷一为两小时笔试，满分105分，占 A-Level 总成绩的35%。该试卷考查物理化学相关章节（1.1–1.7）及全部无机化学（2.1–2.6），并涉及相关实验技能。

Question styles include short-answer questions, data response questions and extended response questions. Students are expected to apply their knowledge to unfamiliar contexts and to demonstrate mastery of the key quantitative methods.

题型包括简答题、数据回应题和扩展回答题。学生需要将知识应用于陌生情境，并展示对关键定量方法的熟练掌握。

3. Paper 2: Physical and Organic Chemistry | 试卷二：物理化学与有机化学

Paper 2 is also a two-hour written examination, worth 105 marks and 35% of the A-level. It covers physical chemistry topics 1.1–1.7 again, but focuses specifically on their application in physical chemistry, alongside all organic chemistry topics (3.1–3.16) and related practical skills.

试卷二同样是两小时笔试，满分105分，占 A-Level 总成绩的35%。它再次覆盖物理化学专题1.1–1.7，但侧重其在前沿
