As part of this component of the Chemputer, I have included a tutorial/guide to the VSEPR rules.
Use this form to build your compound. As an example, the default settings show you how to complete the form for a neutral sulphur compound complex [SCl2O]. There are a number of points:
- Enter the symbol of the central element
- For attached groups or atoms, you can:
- use abbreviations such as 'En' provided these start with a capital letter and contain no other capital letters. Thus, En and Thf are OK, en and THF are not.
- use formulae such as PPh3
- use names such as chloride or chloro
- use formulae such as C7H7 (but care, does this mean benzyl or cycloheptatrienyl?)
- If the program at the other end of this form doesn't understand any entry or if the entry is ambiguous as in the C7H7 case above, it will try and tell you.
