SAT2化学题（在线等解答）1. The molecule SO2 has a net dpolenet dipole 是什么?请详细解释一下.2. oxygen has higher electronegativity than sulfer答案说这句话错了,为什么错了?氧元素电负性难道不是比硫大吗? 谢谢!
网友回答
我知道第一个,第二个就不懂,我也觉得应该是对的,net dipole means that there are multiple dipoles in given molecules,eg.SO2.Because oxygen is more electronegative than sulfur,a dipole is formed,which is a vector,pointing towards oxygen.When you considered the Lewis structure,there are two dipoles with a lone pair,the lone pair pushes more than S-O bonding,so it is a bent shape,therefore SO2 is polar.P.S.都考SATII了,我就发英文了
