no add implicit/explicit hydrogen option

Hi, unfortunately there does not seem to be an option to add explicit hydrogens onto the structure on my MarvinSketch (in the structure menu). Could I please get some assistance in how to fix this?

Cheers 

Hi,

It must be there (Structure > Add > Explicit Hydrogens) unless your menu configuration file removes it (i.e. the menupoint was removed using the View > Customize option, or a server side configuration is used, which does not contain this menupoint).

Best regards,
