SANDERSON电负性与HmR型氢化物的酸碱性

Sanderson's Electronegativity and Acid-Alkali of HmR-type Hydride

本文应用sanderson电负性理论,计算了周期表中P区元素氢化物的电荷分数,根据电荷分数的推论和电荷分数值对这些氢化物在水中的行为进行了分类,提出与电荷分数有关的计算PK_(?)的经验公式,计算了部份HmR型氢化物在水中的PK_(?)值,与实验值较为接近。

With Samderson's electronegativity theory, the partial charges of hydride in parea of the periodu tabcl are counted. Based on the way of deducting partial charges ion and charge fraction value, the activity of hydride in water is classified, so that a formula to caculate pka in relation to partial charges has been advanced.It has been discovered that PKa value of part of HmR-type hydride in water is close to experimental value.
