So we are supposed to draw isomers of pen tail, which is an alkan ultimately with the formula c5h12.
00:15
So this explains that for 5 carbon atoms there would be 12 hydrogen atoms.
00:23
So let us draw the very basic structure first.
00:26
So let us draw the six, sorry, five carbon atoms in a chain.
00:32
Now let us place the hydrogen atoms so that the valency is completed.
00:44
Here we can see that the valency of the carbon is 4 as there is no double bond.
00:53
All of the valencies are completed by the hydrogen or the corresponding or consequent carbonode.
01:01
So this is the structure of n -pectane.
01:07
In the straight line expression, we can also show it in this form, which is this one, which is 1, 2, 3, 4 and 5.
01:18
So each corner represents a carbon atom.
01:23
This is another way of representing the isomer or drawing the structure.
01:29
Now, the another form is the isopentane in which one of the carbons is shifted to.
01:39
One of the bonds present in the middle of the chain.
01:44
So somewhere here.
01:46
So let us draw that structure.
01:48
So the isopentin.
01:54
So for that, let us draw four carbon atoms.
01:59
Out of which either the fifth carbon atom will be joined here or here.
02:06
That is in between the two atoms...
