In the database, the entry is currently listed as n-butane C4H10
. In this dev version, I was able to build n-Butane | C4H10
on the 3rd screen due to recent changes in https://github.com/phetsims/build-a-molecule/issues/148.
In https://github.com/phetsims/build-a-molecule/issues/153#issuecomment-580072157, we decided to use C4H10
for n-Butane
referencing the PubChem entry here where n-Butane
is listed as a synonym for Butane
.
@arouinfar Should we rename the entry n-Butane
to Butane
? I don't know what would be the more commonly accepted name, despite both being the same in PubChem.
If you can build it now, we should replace the current public version. Thanks, Kathy. I am not concerned about the name, just could not even build it. Please post the new version. Thanks!

Got it I'll follow up with @mattpen to post a new version. Unassigning other parties.
@Denz1994 the molecule name should remain n-butane
. While this molecule is commonly referred to as "butane" the "n" denotes the geometry of the molecule (straight chain). The other structure sharing the same chemical formula is iso-butane which contains a central carbon connected to three other carbons.
As an aside, we decided to get rid of n-propane
and call it propane
in #131, but there is no other way to arrange the carbon atoms in C3H8.
Thanks for the explanation @arouinfar. This change was included in the dev version in this comment. I'll close this issue.
I tried to build Butane - which is possible given the atoms - but for some reason it doesn't seem to allow it. Can you look at the database to see that it is included? And if not figure out why, or if it is, why I can't build it? Thanks! Also assigning JO, since you both worked on the database together.
