课程名称：有机化学：如何构建人类 课程概述：在您开始学习有机化学时，可能会被大量的化合物、名称、反应和机制所淹没。本课程的目标是将这些材料进行整理，并展示大多数有机化学基本由几个基本原则及其多种扩展和应用组成。 第一部分：结构与键合 我们将回顾从普通化学中提取的关键概念，以帮助您在有机化学中的成功，包括原子的电子结构、路易斯结构和八隅规则、键合类型、电负性以及形式电荷。我们将预测涉及C、H、O、N和卤素的共价和离子键的模式，识别共振稳定结构，并比较其共振形式的重要性。学习绘制和解释常用的有机化学结构式，包括凝聚结构式和线角结构式。预测有机分子的杂化和几何形状，并识别异构体及其差异。 第二部分：酸碱与功能团 我们将识别导致化合物极性和氢键形成的分子特征，预测物理性质（如沸点和溶解度）的普遍趋势，识别酸、碱、电亲体和亲核体，比较它们的强度并根据结构和键合、Ka和pKa值预测反应。在路易斯酸碱反应中识别亲核体和电亲体，并使用弯曲箭头显示电子的流动。识别有机化合物的基本类别。 第三部分：烷烃的结构与立体化学 我们将绘制和命名烷烃的异构体，解释它们物理性质的趋势，绘制烷烃的构象，比较它们的能量，并预测最稳定的构象。绘制和命名环烷烃的异构体，并解释环应变；同时绘制环烷烃的构象，比较其能量，并预测最稳定的构象。 第四部分：化学反应的研究 我们将提出机制并解释简单反应（如自由基卤化）的步骤。 该课程旨在为学生提供有机化学的基础知识，以帮助他们理解和应用这些基本原则。
As you begin your study of organic chemistry, you might feel overwhelmed by the number of compounds, names, reactions, and mechanisms that confront you. The goal of this course is to organize the material and to show that most of organic chemistry consists of a few basic principles and many extensions and applications of these principles. In Section 1: Structure and BondingWe will review concepts from general chemistry that are essential for success in organic chemistry, such as the electronic structure of the atom, Lewis structures and the octet rule, types of bonding, electronegativity, and formal charges. Predict patterns of covalent and ionic bonding involving C, H, O, N, and the halogens. Identify resonance-stabilized structures and compare the relative importance of their resonance forms. Draw and interpret the types of structural formulas commonly used in organic chemistry, including condensed structural formulas and line-angle formulas.Predict the hybridization and geometry of organic molecules based on their bonding. Identify isomers and explain the differences between them.In section 2: Acids and Bases and Functional GroupsWe will identify the molecular features that cause compounds to be polar and to engage in hydrogen bonding. Predict general trends in physical properties such as boiling points and solubilities. Identify acids, bases, electrophiles, and nucleophiles. Compare their strengths and predict their reactions based on structure and bonding, as well as Ka and pKa values. Identify the nucleophiles and electrophiles in Lewis acid-base reactions and use curved arrows to show the flow of electrons. Identify the general classes of organic compounds.In section 3: Structure and Stereochemistry of AlkanesWe will draw and name the isomers of alkanes, and explain the trends in their physical properties. Draw alkane conformations, compare their energies, and predict the most stable conformations. Draw and name the isomers of cycloalkanes, and explain ring strain. Draw the conformations of cycloalkanes, compare their energies, and predict the most stable conformations.In section 4: The Study of Chemical ReactionsWe will propose mechanisms and explain the steps for simple reactions such as free-radical halogenation.
