(Z)1-2-di iodo ethene?

Answer 1

I think your correct as there is a iodine on both the 1 and 2 carbons and I think that would be correct IUPAC notation, but I am not in organic chemistry just basing this off knowledge from AP chem from last year.

Answer 2

I think that Z means same side, but this looks like opposite sides.

Answer 3

And between numbers are commas, not dashes.

Answer 4

Z is zusammen : together=same side
E is entgegen : opposite
