Background Carbon monoxide (CO) is a colorless, odorless gas produced by incomplete combustion of carbonaceous material CO is formed as a by-product of burning organic compounds
Compounds having two carbonyl groups separated by an intervening carbon are called β-dicarbonyl compunds, and these compounds are highly versatile reagents for organic synthesis
一、 紫外吸收光谱的产生 formation of UV 二、 有机物紫外吸收光谱 ultraviolet spectrometry of organic compounds 三、金属配合物的紫外吸收 光谱 ultraviolet spectrometry of metal complexometric compounds
Energy and the Relative Stability Kinetic energy is the energy an object has because of its motion. Potential energy is stored energy. It exists only when an attractive or repulsive force exists between objects
Functional groups The structural features that make it possible to classify compounds by reactivity are called functional groups. A functional group is a part of a larger molecule and is composed of an atom or a group of atoms that have a characteristic chemical behavior. The Chemistry of every organic molecules
1858 ~ 1861, Kekulé, Couper, and Butlerov, laid the basis for one of the most fundamental theories in chemistry: the structural theory. Valence(化合价): C — tetravalent; O — divalent; H — monovalent
