1. | A polar molecule. |
| 偶极的分子 |
|
|
| |
2. | The two hydrogen atoms form a polar molecule, that is, one with a slightly positive end and one with |
| 两个氢原子构成了一个极性氢分子,一个略带正极,一个略带负极. |
|
|
| |
3. | non polar molecule |
| 无极分子 |
|
|
| |
4. | If a non-polar molecule is subjected to an electric field, the electrons and nuclei are displaced and |
| 如果一个无极分子被置于电场作用之下,则电子和核发生位移,从而产生一偶极矩。 |
|
|
| |
5. | A molecule where the centers do not coincide is called a polar molecule. |
| 正负电荷中心不重合的分子称为极性分子。 |
|
|
| |
6. | reactions therefore seeks a positive centre, such as the nucleus of an atom or the positive end of a polar |
| 亲核试剂 (1923): 含有用于成化学键的电子对,在化学反应中寻求正电中心(如原子核或极性分子的正端)的原子或分子。 |
