Research 2 common, polar molecules and 2 common nonpolar molecules. draw their molecular structure and explain how the structure makes each molecule polar or non polar

A water molecule is a polar molecule because of its shape. Its one side is positively charged, while another one side is negatively charged. Two hydrogen atoms and one oxygen atom makes up the molecule. Because the atoms share electrons, the bonds between the atoms are called covalent bonds.

Since its bonds are symmetrical, carbon dioxide is nonpolar. The bonds between the carbon and two oxygen atoms are polar; however, the entire molecule is nonpolar because the partial charges cancel each other.

Hydrogen and chlorine are the two different molecules that makes up HCI. It is nonpolar when a covalent compound is compound among the same elements or bonds between H and C. On the other hand, it is polar when there are two or more different elements present.

Four Carbon-Hydrogen single covalent bonds is contained in methane’s molecule and these covalent bonds are specified as nonpolar covalent bonds. There is no charge separation (dipole moment) due to the equal sharing of electrons.
