## Step 1<br />A polar covalent bond is a type of chemical bond where a pair of electrons is unequally shared between two atoms. This is due to the fact that one atom has a stronger attraction for the electrons than the other. <br /><br />## Step 2<br />The atom with the stronger attraction for the electrons is said to be more electronegative. This means it has a greater pull on the shared electrons.<br /><br />## Step 3<br />As a result of this unequal sharing of electrons, the molecule has a positive end (where the less electronegative atom is) and a negative end (where the more electronegative atom is). This creates a dipole moment, which is characteristic of a polar covalent bond.
