implicit hydrogens in marvinsketch

Hello,

I read some other posts that we were going to be able to remove these implicit hydrogens by going to the Structure > Remove > Remove Explicit Hydrogens option.  When I tried that, it did not remove the hydrogens from my structure.  I even tried to highlight the entire structure thinking that that would do the trick, but it did not.  It is kind of frustrating when I want to view the structure without the hydrogen at all.  Couldn't you guys make it an option in preferences to turn implicit/explicit hydrogens on or off? Anyway, how do I resolve my problem?  Thank you in advance for your help.

 

Dear Roberto,

the Remove explicit hydrogens options converts explicit hydogens to implicit hydrogens. That is, what you have drawn as -O-H (with a bond between O and H) will look as -OH (without a bond). To "switch off" these implicit hydrogens, you have to use the View -> Implicit hydrogens -> Off. Then -OH will be displayed as -O.

Thank you so much.  I  must have overlooked that option.  Again, thank you.

The problem with  the View -> Implicit hydrogens -> Off option is that it doesn't seem to actually remove the hydrogens.  It just makes them no longer visible.  I need a way to totally remove them.  I'm trying to draw the two common structures of bisulfite.  Sorry to comment on such an old post.  

Dear Jbrew!

 

   Switching Implicit Hydrogene visibility on or off is only a visibility option. I attach a picture where I tried to draw the structures I have found on wikipedia. I have drwn this with all implicit hydrogens visible, but I had to change the valance of the atoms to get rid of some implicit hydrogens. I also attache the source of the drawing.

   I hope it helps.

Hi,

Could you explain me please  why is not enough that you cannot see these hydrogens?

Best,
