I am trying to name the molecule pictured below. I thought it would be 5-bromo-4-isopropyl-2-methylhex-2-ene, but googling that name does not show any results, which makes me think it is not right. Can anyone suggest what I might be doing wrong?


  • This is how I would be happy to name it, but there are IUPAC rules that you need to look up about systematic naming. You could look at ChemSpider and try the molecular formula; you will find very many compounds, however. – porphyrin Sep 14 at 8:53
  • The name is really not the correct one, from two major reasons - substituents given by prefix, like methyl and bromo, or bromoethyl, have the same priority (there's no priority), and because of rules P-45.2.1, P-45.2.2 – mykhal Sep 14 at 11:34
  • @mykhal Actually, you will need Rule P-45.2.3. – Loong Sep 26 at 19:43
