Showing carbon atoms

I use other molecule sketching programs and all of them have an option to show all carbon atoms. In ISISDraw, you can choose atoms as 'C' or 'C (show)'.





When drawing in Marvingsketch, I notice it defaults to hiding carbon atoms which are not attached to hydrogens. How to I force Marvinsketch to show the carbon atoms?

Choose View -> Hydrogens -> All. It will show C atoms and the implicit H atoms attached to each C.





From a jsp page, use:





msketch_param("implicitH", "all"); // default is heteroterm





To show C atoms without showing the implicit H atoms is much more difficult, but you probably don't want to do that, anyway.

Thanks - that's made things a bit easier but I do want to show the carbon atoms sometimes, even if they are not attached to any hydrogens for example the carbonyl carbon atom in propanone if I'm illustrating electrophilic addition.





Is there no easy way to do this?

Press the More button.


Press the Alias button.


Type C in the text box.


Close the More window.


Click on the C whose symbol you want to display.





The alias information is preserved in MRV, MOL, and ChemAxon Extended SMILES formats, but not in regular SMILES format.

You are officially a genius! Thanks

Do I get a certificate suitable for framing?

Hi Bob,


Thanks for the volunteer support. The moderator is glad if users help to each other.
