Understand that bond polarity depends on the difference in electronegativity between the two atoms forming the bond. The greater the difference, the more polar the bond.
Identify the electronegativities of the atoms involved: Oxygen (O) ≈ 3.44, Nitrogen (N) ≈ 3.04, Carbon (C) ≈ 2.55, and Hydrogen (H) ≈ 2.20 on the Pauling scale.
Calculate the electronegativity differences for each bond: For O–H, difference = |3.44 - 2.20|; for N–H, difference = |3.04 - 2.20|; for C–H, difference = |2.55 - 2.20|.
Compare these differences to rank the bonds from highest to lowest polarity based on the magnitude of the electronegativity difference.
Use this ranking to select the correct order of bonds in decreasing polarity from the given options.
