Hi there.
00:02
The term hydrocarbon refers to compounds that are composed of only hydrogen and carbon.
00:12
So in those compounds, there will be carbon -to -carbon bonds.
00:16
And these are covalent bonds.
00:18
Electrons are shared.
00:20
And there will also be carbon -to -hydrogen bonds that are also covalent.
00:28
So hydrocarbons are covalent compounds.
00:31
I have covalent bonds in them.
00:36
I'm just going to finish out a quick hydrocarbon here.
00:42
Okay, so that would be an example of pentane, which is a hydrocarbon.
00:47
So it is composed entirely of covalent bonds.
00:53
Electrons are shared in each of the bonds.
00:57
And furthermore, all of the bonds are non -polar, meaning that there is pretty equal sharing.
01:06
There is totally equal sharing in the carbon -to -carbon bonds.
01:11
Since they have the same electronegativities.
01:15
And there is pretty similar sharing in each of the carbon -to -hydrogen bonds.
01:21
Electro -negativity difference between the two atoms is only 0 .4.
01:26
So all of these bonds are considered non -polar covalent.
01:33
So as we look at our answer choices, remember we are trying to explain why they do not dissolve or are insoluble in water.
01:41
Well, water is a polar molecule.
