iso is here because the propane can be attached in two ways in the main chain
from the middle carbon or by sideways carbon
okay but then why in 5-propyl there is no iso while propyl is attached in sideways??
wait I'll ask this question clearly again and so you will answer there and can get points too
ISO means second carbon not first carbon
????
:( i didnt got it
if there is a middle carbon of propane is attached to the main chain then it is treated as a substituent
okay i got it but check if I'm wrong -- you mean if there is a middle carbon which has 2 more carbons (means its a propyl) then we use iso to mention that there was a carbon connected in between to the reader
correct????

step 1 - longest carbon chain has 8 carbons, so it is called a octane
step 2 - at carbon numbered 4, you have 3 more carbons attached to it, so it is a PROPYL group.
step 3 - in that 3 carbons, 1st carbon divides into 2 more carbons, so it is called a secondary carbon or iso carbon.
step 4 - so that dividing carbon is called a secondary propyl or isopropyl group.
step 5 - when naming the entire structure you count the main structure carbons which have more attachments to it.
step 6 - at carbon 4 and at carbon 5 there are isopropyl or secondary propyl groups attached.
step 7 - it can be called as 4-isopropyl.
hope that helps
it helped me alot thank you so much
can you help me more please !!! i need help so much right now
i can try
alright :)
oh sorry i forgot to tell this -- check my recently asked question in chemistry and answer it there
it is answered already :-)
yup just right now but there was another ques which I just have asked the "unsaturated- --radical" can you please try to answer that one??
excuse me if you're there then can you please help me??!!!
