KingDraw

KingDraw: A great learning app to sketch reactions, pathways and individual molecules.

KingDraw is a great application that will allow expert chemists, teachers, and students, to create molecules and reactions from a user-friendly interface, by offering them graphical tools that allow them to build simple to complex chemical structures.

The interface is pretty much taken by the editing area, and the graphical chemical structures can be placed and connected using various types of bonds (e.g. simple, double, triple, bold, and wedged), while you are also able to add Acyclic and snaking chains, with predefined groups and chair cyclohexanes.

The application also comes with a 3D module, that will allow you to view the generated compound as a 3D model, with all color-coded elements and molecules, and also comes with integrated cloud support.

Overall, KingDraw is a great learning and teaching application that will allow the users to sketch reactions, pathways, and individual molecules.
