OChem Nomenclature

[Anthem26]

Trying to finish some online ochem homework, but I'm having trouble with this one. I'm suppose to name the compound shown in the diagram attached, but apparently it's not right. Can someone help me with this one? (Diagram: http://imgur.com/n2yGz.png )

[bromonium]

You're basically correct, you just need to specify the number of methyl substituents. It's 1,2-dimethylcyclopentane.

ok thanks, that was my mistake.
