Of the following bonds, which one is most polar? Select one: а. С-N b. C-C С. С-F d. C-H

c. C-F.

Explanation:

Hello, to know the type of bond, you must subtract the electronegativities for each element forming the bond:

a. C-N=3.04-2.55=0.49

b. C-C=2.55-2.55=0

c. C-F=3.98-2.55=1.43

d. C-H=2.55-2.2=0.35

Thus, since for an electronegativity difference between 0.7 and 1.7, the bond is polar, the highest number (most polar), based on calculations is 1.43, that is for c. C-F.

Best regards.
