Title Slide |
Welcome to this Spoken Tutorial on Interchange the Element In the 3D Model. |
| Slide Number 2
Learning Objectives |
In this tutorial, we will learn to,
|
| Slide Number 3
System Requirement |
Here I am using,
|
| Slide Number 4
Pre-requisites |
To follow this tutorial,
|
| Click on the model-kit icon.
Cursor on Methane model |
I have opened the Jmol interface.
Click on the model kit menu to open it. We have a model of methane on the screen. |
| Cursor on the methane molecule.
Cursor on the elements menu. |
I would like to change themethane molecule to borane.
Here, we need to change the central carbon atom to boron. Open the Model kit menu. In the list of elements boron is not included. Hence we need to add boron to the list of elements. |
| Click on the double-question mark icon.
type the symbol for boron as capital “B”. Click on OK. |
Click on the double-question mark icon.
In the Element input box, type the symbol for boron as capital “B”. Click on OK. |
| Cursor on the menu. | When you open the model-kit menu again, boron is already selected. |
| Click on the central carbon atom in the methane model.
Cursor on the boron atom. |
Now click on the central carbon atom in the methane model.
The carbon is now replaced by boron atom. You can see the change in the color of the atom to pink. The valency is automatically adjusted to 3. Hence you will see 3 hydrogens on central boron atom. |
| Cursor on the borane model.
Click on minimize in the model-kit menu. Select exit modelkit mode to close the model kit menu. |
This molecule is borane.
Click on minimize in the model-kit menu to do energy minimization. Now select exit model-kit mode to close the model kit menu. |
| Double click on any hydrogen atom.
Click on the central boron atom. Again double-click on the other hydrogen atom. Cursor on the measurements on the model. |
Let us measure the bond angle.
Double clicking on any hydrogen atom. Click on the central boron atom. Again double-click on the other hydrogen atom. You can see the bond-angle as 120 degrees . This corresponds to the sp2 hybridization found in borane. |
| Cursor on the panel.
Click on the model kit icon. |
I would now like to change the central atom to silicon to create Silane.
Open the model kit menu. Let us add a silicon symbol to the list of elements. |
| Click on the double-question mark icon.
type the symbol for boron as capital “Si”. Click on OK. |
Type “Si” in the element input box and click OK. |
| Click on the central boron atom on the panel. | Now click on the central boron atom on the panel.
Observe the color change of silicon atom. It is seen as light brown in color. |
| Cursor on the panel. | The valency of silicon is 4.
Hence the hydrogens are also adjusted automatically to 4. This molecule is Silane. |
| Click on minimize in the model-kit menu. | Click on minimize in the model-kit menu to do energy minimization.
Now select exit modelkit mode to close the model kit menu. Let us measure the bond angle. |
| Click on model kit menu. Select Nitrogen from the element list . Click on central silicon atom. | Following the same steps I have converted the Silane model to ammonia.
Let us measure the bond angle. In this way we can create 3D models of a number of covalent inorganic molecules. |
