So in the question they asked you to draw the newman projection structures.
00:04
Newman projection structures.
00:10
Now see how will you draw? so here we will draw the two.
00:15
This is one carbon and it has the front carbon represented like this.
00:23
Carbon attached to ch3 three times.
00:28
Here it is attached to ch3.
00:31
Here it is attached to ch2, ch3.
00:35
Now the another carbon, it is represented as another bond, it has eh, it is attached to ch3 and this is attached to eh.
00:46
So this structure we also can draw this group, we can expand this group and it is nothing but we will write just here.
00:56
This group we can represent it like carbon attached to ch3, ch3, ch3, this attached to this and this and this one it is ch3 and this one ch3 and this one ch2 ch3 now the remaining are as it is that is hydrogen here it is hydrogen and here it is ch so if you want to draw the skeletal diagram of this one we can draw the skeletal diagram is like this this attached to one methyl group here one methyl group here one methyl group and this is the ethyl group.
01:41
So if you number that number one, number two, number three, number four, number five.
01:47
And when we write down the name, the name is like this, the name is three ethyl, two comma two comma three trimethyl pentane...
