Hello everyone,

I'm having trouble at coming up with the name of the last four chemicals - I know whether they're E or Z isomers, but I don't know how to do the rest of their names...

Can anyone help me with these please?

The link to the display formulas are http://www.chemguide.co.uk/basicorg/questions/q-eznotation.pdf

You could have just read up on this. You just need to put or E or Z at the start of the name as you would with cis or trans.

To be clear, this question is not actually asking you for the rest of their names but rather if the isomers drawn are E or Z. If you're interested in actually fully naming the compounds, consider something like http://www.acdlabs.com/iupac/nomenclature/ - though this is a little technical.
