i am trying to draw a structure using IUPAC.
the structure i am trying to draw is
     4-isopropyldecane

i have the 4-propyldecane drawn, but i am not sure what the iso group is supposed to look look like or where it is supposed to go.

take this phrase from wikipedia:

The prefixes iso, sec and tert refer to the number of carbons connected to the primary carbon (also known as RI ("R prime"), the carbon that is connected to R). Iso means one, sec- means two and tert- means three. (http://en.wikipedia.org/wiki/Butyl)
