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,是化学学科的一个分支,它的研究对象是有机化合物。 什么是有机化合物呢?早期化学家将所有物质按其来源分为两类,人们把从生物体 (植物或动物)中获得的物质定义为有机化合物,无机化合物则被认为是从非生物或矿 物中得到的

1.分析范围广(气体、液体、固体) 2.测定分子量,确定分子式 3.分析速度快,灵敏度高 4.各种联用技术 5.新的电离、检测技术 5.1 基本知识 5.2 电离过程 5.3 质量分析器 5.4 亚稳离子及其检测

ou have already had considerable experience with carbanionic compounds and rgani their applications in synthetic organic chemistry. The first was acetylide ion in Chapter 9, followed in Chapter 14 by organometallic compounds-Grignard reagents, for example-that act as sources of negatively polarized carbon. In Chapter 18 you learned that enolate ions-reactive

the preceding chapter you learned that nucleophilic addition to the carbonyl group is one of the fundamental reaction types of organic chemistry. In addition to its own reactivity, a carbonyl group can affect the chemical properties of aldehydes and ketones in other ways. Aldehydes and ketones are in equilibrium with their enol isomers
