Sorry, this is driving me crazy
what is the difference between ISO and NEO?

ie when applied to butyl, propyl, etc?

NEO = most branched structure?
ISO = a secondary structure drawn a different way?

thanks

iso is when u have branching of two methyls (plus another attachment to rest of molecule).. and neo is the branching of 3 methyls (plus another attachment to rest of molecule).

i dunno if i explained it well enough 😳

neo= just a straight chain like you said
iso = same, which is symmetric structure. The other component always attaches to the line of symmetry. Just draw out the lewis structure and you will know what i mean.
