Let me draw the structure first.
00:02
We have a bond line formula which is drawn as so this is the bond line formula we have okay so here this one this one this one this one this one this one this one this one this one this one this one this one and this one so these all are the carbon we have.
00:46
So it can be drawn with the help of carbon and hydrogen atoms.
00:50
It can be drawn like carbon atom here.
00:55
Then it is further attached to another carbon atom, then to another carbon atom, then another carbon atom, then another carbon atom.
01:06
Then we have further more carbon atoms like this.
01:14
So now completing the valencies, keeping in mind that carbon is tetravalent in nature.
01:18
Carbon can make four bonds at one time, so we will complete the valency with the help of hydrogen atoms.
01:23
So here we require three hydrogen atoms.
01:25
Here we require two hydrogen atoms.
01:27
Here we require one hydrogen atom.
01:29
Here we require one hydrogen atom.
01:31
Here we require two hydrogen atoms.
01:33
Here also we require two hydrogen atoms.
01:43
Then here we require three hydrogen atoms.
01:46
Here we require three hydrogen atoms.
01:48
Here we require one hydrogen atom, two hydrogen atoms.
01:53
Here and here also two hydrogen atoms and here three hydrogen atoms so this is the complete structure okay so now the basic rule for the iepc naming is select the longest carbon chain possible and when we are doing so we should always make sure that the carbon atoms containing substituents should be given the least position possible so now if i start from here one two three four five six and 7 so now i have a carbon atom chain main carbon atom chain with 7 carbon atoms and i have also ethyl group set as to it so i you p -a -c name that is 3 -4 die ethyl so here we have ethyl so here we have ethyl okay when the same substituent is being repeated for more than one time we use prefixes here ethile group is being repeated for two times so we use die prefix so it is three four diethyl and now i have seven carbon atoms in the carbon chance so the prefix for the carbon at atom chan will be hap okay so this is happed here and since all the carbon atoms are being connected by single bonds so this is alkan chan and that's why the suffix is a okay, so this is three four diethyl haptane now moving on to the next part we have a benzene ring and now to this benzene ring i have substituents attached like this okay so here also i can draw the structure like this benzene ring i have and i have this carbon atom okay one two three and this one so these are the carbon atoms so carbon atom then it is further attached to two more other carbon atoms so here we have one hydrogen atom here we have three hydrogen atoms and here we have three hydrogen atoms so then we have a carbon atom containing three hydrogen atoms so now this is a complete structure okay now so now for the substituents if i count from here one two three now the thing is which substituents should be written first while i am writing the ipsc name.
04:50
So the answer is you will prefer the alphabetic order.
04:55
So alphabetically, this is the alkyl group i have containing three carbon atoms...
