An acid is a substance that can donate (or lose) a proton, A base is a substance that can accept (or remove) a proton

Carbon’s ability to form strong covalent bonds to other carbon atoms is the single property of the carbon atom that — more than any other—accounts for the existence of a field of study called organic chemistry. Carbon’s ability to form as many as four strong bonds to other carbon atoms, and to form strong bonds to hydrogen, oxygen, sulfur, and nitrogen atoms as well

The reactivity of organometallic compounds increases with the percent ionic character of the carbon-metal bond. RLi and RMgX are of great importance in organic synthesis

Acyclic Conformational Analysis-1 Ethane, Propane, Butane & Pentane Conformations Introduction to Allylic Strain Reading Assignment for week

一、有机化合物和有机化学 1、有机化学、有机化合物的定义 有机化学（organic chemistry）是研究有机化合物 的来源、制备、结构、性能、应用以及有关理论和方 法学的科学。 自从拉瓦锡（Lavoisier.A.L)和李比希（Von Liebig.J.F) 创造有机化合物的分析方法之后，发现有机化合物均含 有碳元素，绝大多数的含氢元素，此外，很多的有机化 合物还含氧、硫、氮等元素

3.1 Introduction Vitamins are classically defined as a group of organic compounds required in very small amounts for the normal development and functioning of the body. They are not synthesised by the body, or only in insufficient amounts, and are mainly obtained through food (Machlin and Huni, 1994). There are thirteen vitamins: four are fat-soluble, namely vitamins A (retinol)
