In this lesson you learned about two types of bonds: nonpolar covalent and polar covalent. Nonpolar covalent bonds are a type of chemical bond where two atoms share a pair of electrons with each other. Polar covalent bonding is a type of chemical bond where a pair of electrons is unequally shared between two atoms.
You can tell if a molecule is polar based on the bonds (i.e. ionic bonds = always polar whereas covalent bonds are only polar when there is an equal distribution of electrons) Examples of nonpolar molecules include hydrocarbons (fats: i.e. oils), which do not dissolve in water.Hope this helps! And good luck :).ou can tell if a molecule is polar based on the bonds (i.e. ionic bonds = always polar whereas covalent bonds are only polar when there is an equal distribution of electrons) Examples of nonpolar molecules include hydrocarbons (fats: i.e. oils), which do not dissolve in water.
