Dr. Haxton says the O-O bond is polar and the C-C bond is nonpolar. A good student would say ...

a. No, both bonds are highly polar.

b. Yes. O attracts electrons more strongly than C.

c. Right! O is electronegative, so O2 is polar.

d. Wrong again, Ralph. Both bonds are nonpolar. When two atoms of the same kind form a covalent bond, they share electrons equally because their electronegativity is the same.

e. No way. C is more electronegative than O.

Answer: d. Wrong again, Ralph. Both bonds are nonpolar. When two atoms of the same kind form a covalent bond, they share electrons equally because their electronegativity is the same.

Explanation:

Often when O and H are present in the substance at (opposite) ends (of the electronegativity scale), the polarity observed is very large, we can safely say the substance have a polar bond in it.
