Vedclass · Answer

(D) The polarity of a covalent bond depends on the difference in electronegativity between the two bonded atoms. The greater the electronegativity difference,the higher the polarity of the bond. The electronegativity values of the atoms involved are: $C = 2.55$,$O = 3.44$,$Br = 2.96$,$S = 2.58$,and $F = 3.98$. The electronegativity differences are: $C-O: |3.44 - 2.55| = 0.89$ $C-Br: |2.96 - 2.55| = 0.41$ $C-S: |2.58 - 2.55| = 0.03$ $C-F: |3.98 - 2.55| = 1.43$ Since the difference is highest for the $C-F$ bond,it is the most polar bond.

Which of the following bonds has the highest polarity?
