Did you know?

You can block substituents at a particular position by drawing explicit hydrogen atoms.
You must add a bond and then add a hydrogen using the X atom function (symbol H). Click on the 'X', a window will open. In this window you can also enter other atoms i.e. Si, Na, Se, etc.

Total Hits: Increasing the total hits will cause slower search times.
