would a c18 hydrocarbon be polar or nonpolar--y or y not?
Answers and Replies
Hydrocarbons are composed only of carbons and hydrogens,
and C-H bonds are considered nonpolar. No hydrocarbon contains a polar structure.
Of course, there does exist an EXTREMELY small and probably insignificant difference in the electronegativities of hydrogen and carbon, and thus you have quite the tiny polarity. Too tiny to be practical.
nate808, all hydrocarbons are considered nonpolar.
