What is the polarity of carbon carbon bonds in alkanes?

Alkanes contain only carbon-carbon and carbon-hydrogen bonds. Because carbon and hydrogen have similar electronegativity values, the C-H bonds are essentially nonpolar. Thus, alkanes are nonpolar, and they interact only by weak London forces.
