Preferred IUPAC name[edit]

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

The IUPAC name is 2-methylpropane. I have no idea what is meant by "preferred" because IUPAC is very strict with its nomenclature. There is only one correct IUPAC name for each different, unique molecule.
There are situations where multiple chemical names can be consistent with IUPAC nomenclature rules. See preferred IUPAC name for details. -- Ed (Edgar181) 15:15, 7 July 2016 (UTC)

Neobutane[edit]

Could this also be called neobutane? Like neopentane? I'm no expert in O-chem or naming structures. I just wanted to learn what the difference is? — Preceding unsigned comment added by Aglo123 (talkcontribs) 16:54, 28 May 2013 (UTC)

Variable melting point?[edit]

What exactly does a variable melting point mean? Surely it has only one melting point at 1ATM. If those are for different pressures then it's imperative that you list them for those figures to be meaningful. -- 213.176.153.100 (talk) 13:48, 16 February 2016 (UTC)

I added in correct/precise boiling and melting points referenced to a reliable source. -- Ed (Edgar181) 14:21, 16 February 2016 (UTC)

Refrigerant use[edit]

The part "Refrigerant use" here sounds like a payed FUD from the early time of the refrigerant battle of the 1990s.
In Europe the R600a is the standard Refrigerant for alle domestic refrigerators since the 90s.
The Refrigerant R134a is not in use for domestic refrigerators in the EU.
The articel sounds like that the Hydrocarbons are a permanent risc in every household.
Since the introducion of the hydrocarbons millions of domestic refrigerators where produced and wrecked.
How many caused a damage because of the use auf hydrocarbons?
In my fridge is a quantity of ca. 50 Gramm of R600a.
