[edit] Preferred IUPAC name
The article and the info box appear to disagree on the IUPAC name. The article says "The position number (2-) is unnecessary because it is the only possibility in methylpropane", however the "Preferred IUPAC name" given in the info box is 2-methylpropane, and methylpropane is listed under "Other names". If the 2- is indeed unnecessary, shouldn't methylpropane be the preferred IUPAC name and 2-methylpropane either be dropped, or listed under other names?
Also, which takes precedence, the "IUPAC name" or the "Preferred IUPAC name"? My English language interpretation says that "preferred" would rank higher than the other. If so, shouldn't it be above "IUPAC name" in the info box?
In conclusion, my suggestion would be to change the info box to the following, in this order, but I don't have enough confidence with the IUPAC nomenclature to make the change.
IUPAC name: methylpropane
Other names: 2-methylpropane; isobutane
