Alevel科目考试复习以及考试战线比较长,同学们在复习时多多少少都有一定的压力。今天锦秋A-Level来跟大家讲讲那些值得同学们好好复习的A2化学知识点梳理,一起来走进今日份给大家准备的Alevel化学知识点吧!
Chemical Energetics
Free Energy and Entropy
Lattice Enthalpy, Ionisation Energy, Born-Haber Cycles, Hydration Enthalpy
化学能量部分,学员在as阶段已经学习了,但是这A2部分要深入考察学员对于自由能和熵变的理解,关注考察晶格能的概念,电离能的定义和意义,Born-Haber循环和水合焓。
Electrochemistry
Electrode Potentials - Redox, Half Cells, Electrochemical Series
电化学的部分,我们在复习的时候要关注电极电势和金属的活泼性顺序。
Equilibria
Acids and Bases - Buffer Solutions and Uses
Acids and Bases - Strength, pH Curves, Indicators
Equilibrium Constants - Kc, Kp
学员们已经了解了化学平衡的概念,但是在A2部分要能量定量的去理解平衡的程度,明白平衡常数的意义,公式。理解酸碱度,酸碱指示剂和缓冲液。
Reaction Kinetics
Chemical Equilibrium and Industrial Applications
Rates of Reaction - Rate Equation, Order, Rate Constant (k), Arrhenius Equation and Rate Determining Step
关于反应速率,学员们要了解速率方程,速率常数和限速步骤。
Group 2
Group 2 - Trends, Reactions and Properties
第二主族元素的规律,反应和性质是考察的一个要点。
Transition Elements
Reactions of Transition Metal Ions - Cobalt, Copper, Iron, Manganese, Chromium, Silver and Vanadium
Transition Metals - Oxidation, Coloured Ions, Colorimetry, Ligands, Coordination Number, Isomerism in Complexes and Catalysis
同学们在复习的时候,要了解常见的过渡金属,知道过渡金属涉及的化学反应,配合物的组成和性质。
Introduction to Organic Chemistry
Amines, Amino Acids,
Benzene - Structure, Reactions and Substitution
Friedel-Crafts Reactions - Alkylation and Acylation
Isomerism - Structural, E_Z, Optical and Stereoisomers
有机物部分,在A2我们要关注胺类物质,对于氨基酸性质和多肽部分,学员可以弱化。只要了解蛋白质的三级结构。苯类物质结构特征,常见反应要关注。物质的光学结构是考试重点。
Hydroxy Compounds
Phenol - Structure, Preparation, Uses and Reactions
酚类物质要了解结构,制备和应用。
Carboxylic Acids and Derivatives
Aldehydes and Ketones - Properties, Reactions, Identification and 2,4-DNP
Carboxylic Acids, Esters and Derivatives
Friedel-Crafts Reactions - Alkylation and Acylation
对于羧酸及其衍生物类,学员们要关注结构,性质和常见的化学反应。聚合物的性质与合成也要关注。
Organic Synthesis
Organic Synthesis - Extending Carbon Chains, Friedel-Crafts Reactions and Chiral Synthesis
有机合成是利用延伸碳链的方式改变物质组成,Friedel–Crafts reaction要会画出来机理图。
