Take a look at water. Water is bound to two hydrogens and also has two lone pairs of electrons. Because of the two loan pairs, the molecule has a tetrahedral bent shape. In order to determine whether or not the molecule is polar, you have to look at the partial charge vectors. First...
A molecule will have dipole–dipole forces if it is polar. To determine whether a molecule is polar, (1) determine whether the molecule contains polarCONCEPTUAL PLAN
They form a polar molecule,___,one with a slightly positive end and a slightly negative end. 他们构成了一个极性分子,也就是说,一个带有轻微的阳性,另一个是轻微的阴性。 that is即that is to say,在句中作插入语,意为“也就是说”,相当于in other words。 ①He will leave Japan next Saturday...

What kind of molecule is water? What kind of elements form polar covalent bonds? Is H2CO polar or nonpolar? What intermolecular force is responsible for the attraction between an ion and a polar molecule? What is a tetrahedral molecule?
aFirst, the hydrogen atoms in the water molecule are distributed asymmetrically, causing the water molecule to have a positive side and a negative side: it is said to be polar. 首先,在水分子分布得氢原子不对称地,造成水分子有正面边和消极边: 它被认为极性。 [translate] ...
