Provide an acceptable name for the alkane shown below.
The Attempt at a Solution
I never get these right but....my guess would be 2-dimethyl-5-butononane? My reasoning: the longest carbon chain has 9 carbons so the base name would be nonane, there are 2 methyl groups on carbon #2 and 1 butane group in carbon #5. I'm pretty sure this is not right but could someone please point out my mistakes and give me a method as to how to get it right? Thank in advance :)
