The “Add Hydrogens” function under “Build” did not work. No response after click the button.
The way of draw chemical structure seems different from earlier version. I can not click-and-drag to extend a carbon chain. Instead, I need to add carbon atoms first, and then built bonds. It feels a little bit strange.
I first clicked on the screen, a CH4 appeared (first figure). Then I tried to click on the carbon and drag, a C-CH3 structure formed (second figure). When I tried to click on the second carbon and extend the chain, the only thing happened was the rotation of the C-H bonds (third figure). I also tried if I could add hydrogen on the first carbon with the “Add hydrogen” function, but nothing happened.
