polar covalent compound 极性共价化合物 要判断一种物质是否是极性分子,关键是看正负电荷的中心是否重合,如果重合的话就是非极性分子,不重合的话就是极性分子,判断电荷是否重合的一般方法是看分子结构是否是对称的,如果是对称的,一般是非极性分子,如果不对称一般是极性分子,比如甲烷,它是一种对称的结构,...

Water - H2O Ammonia - NH3 Sulfur dioxide - SO2 Hydrogen sulfide - H2S Ethanol- C2H6O Note ionic compounds, such as sodium chloride (NaCl), are polar. However, most of the time when people talk about "polar molecules," they mean "polar covalent molecules" and not all types of compounds ...
F. Javier Luque, in Theoretical and Computational Chemistry, 1999 3.3 Molecular topology A polar solvent like water is known to have a relevant influence on the covalent structure of polar molecules. This is clearly illustrated by the effect of hydration on the tautomeric equilibria of molecules. ...
An analytical description of the structure of liquid water presents a largely intractable problem. However, a good place to begin is with the chemical structure of the water molecule. First consider the ─O─Hbonds of water. They arepolar bonds. The distribution of electrons in the ─O─Hbond...
