Question

Answer 1

Answer: mark me as brainlist if helpful

Explanation:A polar molecule is one in which one side, or end, of the molecule has a slight positive charge and the other side, or end, has a slight negative charge. This will occur whenever the molecule is not completely symmetric. (Unless, of course, the molecule is a hydrocarbon.)

The other simple case – a molecule that consists of two atoms of the same element – is nonpolar precisely because it is completely symmetric.

Hope u understand this !!
