Ill keep it short. I'm taking an organic chem class and given that times are hard for all, i was hoping i can get away with purchasing the traditional model kit ( Ball and stick) - i was wondering, are there any interactive- user friendly virtual model Kits out there that one can download for free. Something simple yet will allow me to build different structures and extends the utility of molecular models. As i said this is my first Ochem class so im trying to keep it simple. Thanks guys
