Re: (E,Z) vs (cis,trans) naming « Reply #3 on: January 30, 2013, 03:12:55 AM » cis/trans can be ambiguous in the case of tri- or tetra-substituted alkenes because the naming is not strictly associated with priority rules - hence E/Z is preferred.Ambiguity is also a probl...

However, cis-trans nomenclature is still extremely common and it is good for simple alkenes with two couples of different substituents. Very true. You can still use it for disubstituted alkenes and everyone will know what you are talking about. I always try to encourage the use of E/Z thoug...

It can be named by cis but is not recommended by IUPAC with multiple substitution alkenes. This was already discussed and everyone agreed (3E)-3-bromo-4-methylhex-3-ene or E-3-bromo-4-methylhex-3-ene are the correct names for the molecule. For the quiz cis-3-bromo-4-methyl-3-hexene...
