Step 1: Understand what polarity means. Polarity in a bond occurs when there is a difference in electronegativity between the two atoms involved in the bond.
Step 2: Identify the electronegativity values of the elements involved in the bonds. For example, oxygen (O) has a higher electronegativity than hydrogen (H).
Step 3: Compare the electronegativity differences of the bonds in question. The larger the difference, the more polar the bond is.
Step 4: Determine that the O-H bond has a significant electronegativity difference, making it more polar than other bonds with smaller differences.
Step 5: Conclude that the O-H bond is the most polar bond among the options given.
