Enantiomers

Instructions

1. Draw the desired molecule in the JSME panel.
2. Write the proposed IUPAC name in the text field.
3. Click on the button "Check name" to verify the molecule's identity.
4. If the result is wrong, the molecule in the right panel represents the proposed name. A visual check will allow you to identify the differences!
5. For help, it is possible to read the nomenclature rules for many functional groups.

Instructions

1. Select the class of molecules having the desired functional from the drop down menu
2. Select a molecule by clicking on it
3. write the molecule's name in the proper field and click on "Check Answer". At the bottom of the page there are suggestions on how assigning the correct name to the molecule

Rules:

It is possibile to use the already available examples or draw your own molecules.

1) to assign the priority, click on "Initialize".

2) click on the chiral carbon in JSMol and click on the "Chiral Carbon" button

3) repeat the the step 2 assigninig the priority to all the first atoms linked to the chiral Carbon

4) orient the molecule to place the group having priorirty 4 far from the observer

5) Assign the chirality R or S to the molecule
