Reaction mechanism and resonances

The tool for drawing the curved arrows in reaction mechanism and resonances is the electron flow arrow on the left toolbar of the drawing tool.

There are two options to draw the curved arrows when the teacher creates new exercises:

• Direct arrow option: simple electron pushing representation with a curved arrow.
• Show forming bond option: complex electron pushing representation with a curved arrow and a dotted line is drawn to the forming bond.

These options are available under the Exercise settings button for teachers when creating new exercises.

The default option is always the Direct arrow drawing style when creating a new exercise. The teacher needs to set the curved arrow preferences to use the Show forming bond style in each exercise on demand. Exercises in duplicated quizzes will keep their original settings.
The students' drawing tool is set to the same curved arrow drawing style that the teacher set in the Exercise settings.
