Polar/Non-polar Hydrocarbons (1 Viewer)

[Amundies]

Apparently only methane is polar, and every other -ane, -ene and -yne are non-polar. Can someone explain why? The only way I can prove that all of it is non-polar is because I know like dissolves like, and water can't dissolve hydrocarbons. But I'd just like it to be explained in another way.

Methane isn't polar lol

All hydrocarbons are non-polar.

All hydrocarbons minus alcohols are non polar?

Alcohols aren't hydrocarbons- hydrocarbons just have carbon and hydrogen

If you look at the structure of the methane molecule, the bond dipoles cancel each other out, so overall, the molecule is non polar

You already know water is a polar molecule, but because methane has no free acting dipole within its structure, the polar attraction of water will have no effect on the methane molecule, hence it is immiscible.





Methane is non-polar
