Which formula represents a molecule with the most polar bond?a. CO
b. NO
c.HI
d.HCI

Answers

D) HCl is the most polar bond. This is because the electronegativity difference between these 2 elements in this molecule is larger than the other 3 molecules given. The bigger the electronegativity difference, the more polar the bond.

Answer:

HCL

Explanation:

Reference Table S lists the electronegativity of each element. The greater the difference in electronegativity, the more polar the bond. The electronegativity of H is 2.2 and the electronegativity of Cl is 3.2; the difference is the greatest of the choices listed.
