In this video, we want to draw the line structure for an alken with five carbons.
00:07
So an alken means that there's going to be a double bond, which is one degree of unsaturation.
00:18
So if we have five carbons and we want one degree of unsaturation, the number of hydrogens is going to be two times five is equal to 10.
00:27
So we would expect a formula to be c5h10.
00:33
That's our alken, it's pentene.
00:38
And of course, you can have derivatives and branching and whatever, but we'll just draw like n -pentine, like the normal standard one.
00:44
So we can put the double bond anywhere.
00:47
It doesn't specify.
00:48
So let's put it here between the second and the third carbon.
00:51
So every vertex is a carbon.
00:52
So one, two, three, four, five.
00:56
So that's an example of an alken with five carbons.
01:01
And we can verify that there's 10 hydrogen.
01:03
So there's three...
