lan418 Posted September 13, 2006 Share Posted September 13, 2006 O ll / \ l l \_ // O ll / \ ll l \ __ / Ok, this is the hexane molecule with the C=O bond on the top. In the first one, there is a double bond near the lower right and a double bond in the second molecule at the middle left. I'm wondering, as far as isomerism is concerned, is this a cis-trans isomer or a structural isomer and why. On my test i put structural, so i dont know if i'm right. Thanks in advance.

lan418 Posted September 13, 2006 Author Share Posted September 13, 2006 sry, tried to draw a cyclohexane on here. the middle didnt get spaced out and evened. it should be a hexagon with the C=O bond at the tip on top of the hexagon and double bonds on the lower right and middle left, on 1st and 2nd model respectively.

woelen Posted September 13, 2006 Share Posted September 13, 2006 This is a structural isomer. In one molecule, there are 2 C-atoms between the double bonds, and in the other molecule there are 3 C atoms between the double bonds. So, these molecules really have different structures. Next time, use the [ code][ /code] tags for the drawing and insert data between these tags. Then, the molecules look as follows: O ll / \ l l \_// O ll / \ ll l \__/ Link to comment Share on other sites More sharing options...
lan418 Posted September 15, 2006 Author Share Posted September 15, 2006 Yes! i got that right. Ok, ill use the tag next time. Thanks Link to comment Share on other sites More sharing options...
