含N有机物的碱性与N的电负性

THE RELATIONSHIP BETWEEN ALKALINITY AND ELECTRONEGATIVITY IN ORGANIC COMPONDS WITH N

ｊｕｒｉｎｇ等人认为，电负性是原子在成键前单个原子轨道的性质，与轨道中的电子数有关。这一理论，可以用来解释电负性较大的Ｎ，在脂肪胺等有机化合物中能够给出孤电子对，使胺及其衍生物在一定条件下显碱性的原因。

uring and some others found electronegativity is a property of an individual orbital of anatom before a bond is formed, and it is concerned with the number of clcetrons of the or-bital.This theory can be used to explain why atom N with considerably large electronega-tivity can give a pair of electrons in some organic compounds such as aliphat amine and whyamine as well as its derivatives show alkalinity in certain circumstances.
