cis/trans

hi i was wondering how to make a bond cis or trans with the dashed and wedged bonds? please help!

Hi,

Simply draw the double bonds ligands in the desired configuration (see http://www.chemaxon.com/marvin/help/sci/stereo-doc.html ). You can check the recognition of cis/trans situation by displaying e/z labels (see http://www.chemaxon.com/marvin/help/sketch/sketch-chem.html#e-z )

If you have any further questions, please do not hesitate to ask them

regards,

is there a button i can use to make them wedged or dashed that i am not seeing?

Hi,

 

You can draw wedge/dashed bonds by right clicking on the bond in question and select Type in the popup menu or  set the desired draw type in the scrolldown menu of the Tools toolbar.

However dashed/wedge bonds currently determine tetrahedral stereo (R/S) not Cis/Trans: by setting a chiral atoms chirality (right click on the atom, select Stereo / R/S / R or S) the connecting bonds will be automatically modified to reflect the set chirality.
