Naming Alkanes Help?
I have been stuck on this for a bit now. I thought it should be 2-methyl-4propyldecane but mastering chemistry keeps telling me I'm wrong. Any suggestions?
i meant to put a dash in between 4-propyl
I figured it out finally! It was 4-isopropyl-2-methyldecane

The use of the term iso- is not permitted in systematic naming. The problem is the group attached to C4 of the decane chain.
How would you name this if the CH3 side group was not attached - ie you had only a CH2-CH3 group on C4
I suggest: 4-ethyl-2-methyldecane ( the side groups are in alpha order)
Now you have to add the methyl group to C2 of the ethyl group on C4 of the decane chain :
My final suggestion:

we all know iso is not systematic but I dont think your idea of 4-ethyl-2-methyl works either
We need brackets to show the ethyl-2-methyl is attached at 4
so how about 2-methyl-4-(ethyl-2-methyl)decane.?
