Answer:
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.
