How to set the maximal number of double bonds

Hello,

How can I configure the programm that it shows me just maximal three
double bonds in different positions. Example I create two rings
annellated and click on "single or double bonds" so it shows me then
single,1,2,3,4 and so on double bonds in different positions. But I
want to set the programm that it shows me just single, 1,2 and 3 double
bonds in different positions. So how can I set the number of double
bonds in different positions?

 

best regards

Hi,

Would you like to specify, that from several single/double bonds only a fixed number can be double?

Currently it's not possible to set the total number of double bonds.

If you can specify your query using homology groups, then on these groups you can specify the number of double bonds.
