37 Which bond is most polar? (1) C–O
(2) H–O
(3) N–O
(4) S–O
Solution:The polarity of the bond is based on the electronegativity difference. Electronegativity values can be found in Table S on the Reference Table. All we need to do is to find electronegativity value for each element holding a bond. Then, subtract the bigger number from the smaller number to find electronegativity difference. The pair that has the highest electronegativity difference represents the most polar bond.
