There is an alkane compound that has a ramification but when we wrote the name it wasn't written with the prefix "iso" I still remember that the professor said something about when do we consider a branch iso and when not but i totally forgot. Anyone Has an idea? thank you
-
If there are substituents within the group then systematic names must be followed to derive the name.

How would you have named this?

Archer basicly said that already:
The following names are retained for unsubstituted hydrocarbons only:
Isobutane
Isopentane
Neopentane
Isohexane
The link might help you understanding how to name your compounds.
