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.

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong

b. is the answer hoped i
