2012 Final Q6B

Postby Rachel Tat 3E » Sat Mar 12, 2016 5:55 pm

The cycloalkane is named 1-isopropyl-3-neopentylcyclohexane. Would the IUPAC name for this be 1-(methyl-ethyl)-3-(2,2-dimethyl-propyl)-cyclohexane? Just to make sure, is the IUPAC naming always acceptable?

Don't need hyphens within the substitutive name. IUPAC always acceptable.

Yes me and my colleague (@daniel23) just went though this compound and yes we concur that the IUPAC name is 1-(methylethyl)-3-(2,2-dimethylpropyl)-cyclohexane. Just make sure not to write the dashes between 2 names (like methyl-ethyl or dimethyl-propyl). My TA made it a point to tell us about that and said we may get points off if we do.
