Owing to the presence of four fluorine substituents, its reactions differ strongly from the behavior of conventional alkenes such as ethylene. Tetrafluoroethylene dimerizes, giving octafluorocyclobutane. Even normal alkenes and dienes add tetrafluoroethylene in a [2+2] manner. 1,3-Butadiene gives 3-vinyl-1,1,2,2-tetrafluorocyclobutane. 在中心原子杂化类型相同时、由于其配原子的个数可能不同，也就是孤电子对数目会有区别，这时键角也会是有区别的。 这是由于中心原子的孤对电子的电子云肥大，对成键电子对有较大的排斥力，所以孤对电子能使成键电子对彼此离 … See more 当.中心原子种类不同(同主族)，但杂化类型相同、且配原子种类相同时，中心原子的电负性大，成键电子对更靠近中心原子，成键电子对间的斥力要变大，键角要变大。反之，中心原子电负性小的分子，成键电子对要远离中心原子，成键 … See more 当配体基团的体积较大时，基团电子云占据的空间也会相应增大，对相邻的键也会有很强的排斥作用。 如上面的例3中的NH3、·NH2OH … See more 奇分子(有成单电子的分子)是很少遇到，但有可能遇到的一种特殊的分子。由于奇分子的中心原子有一成单的孤电子，与组成和它基本相同、只是比它多一个电子的物种来比较，成单电子对成键 … See more 从上面几方面的比较可以看出，这几个影响键角的因素都是有条件的，在影响键角的能力方面也是有区别的。 在一般情况下，应该先从中心原子的杂化类型来入手。因为杂化类型决定了分子的 … See more scraping grocery stores from internewt
