Let me draw the structure first.
00:03
Ch3, ch3, ch, ch2, ch2, ch3.
00:42
So, this is the structure we have.
00:50
So the basic rule for the ipsa naming is select the longest carbon chain possible.
00:59
So here if i count one, two, three, four, five.
01:11
So here we contain five carbon atoms.
01:16
Now if i count by this one and two and so this is two and this is three and this is four and this is five.
01:25
So by this means also we have five carbon atoms.
01:29
Also, by both of the means we are counting there is a methyl group on the second carbon and ethyl group on third carbon atom.
01:39
Right.
01:40
So by both of the method we are counting.
01:44
By both means we have the same arrangement of the substituent.
01:48
We have the same number of carbon atoms.
01:50
So that's why we can choose either of one of these, any one.
01:56
Okay, both are correct.
01:57
So i am choosing the previous one.
02:09
So here, i -u -p -a -c name...
