Describe the difference between polar covalent bonds and nonpolar covalent bonds using these two molecules - H2 and HCl. Which m
olecule contains a polar covalent bond and which molecule contains a nonpolar covalent bond? Explain your reasoning alongside describing the differences between the types of bonds.
Polar covalent bonds are between atoms with different electronegativities, whereas nonpolar covalent bonds are between atoms with the same electronegativity.
This means that HCl is a polar covalent bond, whereas H2 is a nonpolar covalent bond.
