00:00 | Hello everyone. |
00:02 | Welcome the tutorial on Formation of bonds in GChemPaint. |
00:07 | In this tutorial, we will learn to- |
00:10 | Add bonds to the existing bond |
00:13 | Orient the bonds |
00:15 | Add Stereochemical bonds and |
00:18 | Inverse wedge hashes. |
00:21 | Here I am using Ubuntu Linux OS version. 12.04, |
00:27 | GChemPaint version 0.12.10 |
00:33 | To follow this tutorial you should be familiar with, |
00:37 | GChemPaint chemical structure editor. |
00:40 | If not, for relevant tutorials, please visit our website. |
00:46 | I have opened a new GChemPaint application with Ethane structure. |
00:51 | Let us learn to convert Saturated Hydrocarbons to Unsaturated Hydrocarbons. |
00:58 | Let us copy the Ethane structure and paste it twice on the Display area. |
01:05 | Click on Select one or more objects tool. |
01:08 | Click on Ethane structure to select it. |
01:11 | Press Ctrl +C to copy the structure |
01:14 | and Press Ctrl + V to paste the structures. |
01:19 | Observe that two structures overlap each other. |
01:23 | Let's move the second overlapping structure aside. |
01:27 | Place the cursor on the structure and drag it with the mouse. |
01:33 | Observe the single bond between the carbon atoms in the structures. |
01:40 | Let's first convert single bond to a double bond. |
01:44 | Click on Add a bond or change the multiplicity of an existing one tool. |
01:51 | Click on the existing bond of the second Ethane structure. |
01:55 | Observe that single bond is converted to a double bond. |
02:00 | Number of Hydrogen atoms reduced from 6 to 4. |
02:06 | The new structure is Ethene. |
02:09 | Next let's convert the single bond to a triple bond. |
02:14 | Click on the existing bond of the third Ethane structure twice. |
02:20 | Observe that Single bond is converted to a triple bond. |
02:25 | Number of hydrogen atoms reduced from 6 to 2. |
02:30 | The new structure is Ethyne. |
02:34 | Let us write the names of the structures. |
02:37 | Click on Add or modify a text tool. |
02:41 | Click below the structures. |
02:43 | Enter the names of the structures as Ethane, Ethene and Ethyne. |
02:53 | Next, let us learn about Tetrahedral geometry. |
02:57 | Let's move the structures to a side. |
03:00 | Press Ctrl+A to select all objects. |
03:03 | Click on Select one or more objects tool and drag the structures. |
03:10 | Here is a slide for the Tetrahedral Methane structure. |
03:14 | All the bond lengths are equal to 1.09 angstrom. |
03:19 | In Tetrahedral methane structure, all the bond angles are equal to 109.5 degree. |
03:31 | Now, let's draw Tetrahedral Ethane structure. |
03:35 | Click on Add a bond or change the multiplicity of existing one tool. |
03:41 | Click on the Display area. |
03:43 | Orient the bond in horizontal direction. |
03:47 | On each edge of the bond let us draw three bonds. |
03:51 | Orient the bonds to form a Tetrahedral geometry. |
03:55 | Click on each edge. Then orient the three bonds in different directions. |
04:02 | Likewise let us draw on the other edge. |
04:07 | Let us attach hydrogen atoms at the ends. |
04:10 | To attach Hydrogen atoms to the ends, press capital H. |
04:16 | A sub-menu opens in which we will select H. |
04:21 | Observe that Hydrogen atom appears in the tool box. |
04:26 | Click on Add or modify an atom tool. |
04:29 | Click on all the positions to add hydrogen atoms. |
04:37 | Now let us add Stereochemical bonds to Ethane structure. |
04:42 | Stereochemical bonds available in the tool box are, |
04:46 | Add a wedge bond |
04:48 | Add a hash bond |
04:50 | Add a squiggle bond |
04:53 | and Add a fore bond. |
04:55 | Let us use Add a wedge bond to convert Ethane to a "Stereochemical" structure. |
05:03 | Click on Add a wedge bond. |
05:05 | Then click on all the bonds. |
05:10 | Observe the changes. |
05:13 | Click on Add a hash bond |
05:15 | and then click on the Display area. |
05:19 | Now I will explain about Invert wedge hashes. |
05:25 | Go to Edit menu, navigate to Preferences and click on it. |
05:31 | GChemPaint Preferences window opens. |
05:34 | Click on Invert wedge hashes check box. |
05:38 | If set, the wedge hashes bonds will follow the usual convention. |
05:43 | Narrow end is at the start of the bond and broad end is at the other end. |
05:50 | This helps to visualize the bond correctly. |
05:55 | Default convention in GChemPaint is inverse, because it is more consistent with the perspective rules. |
06:05 | Observe the changes in the Hash bond. |
06:09 | Let us click on Close button to close the window. |
06:13 | Let us change the bonds to Add a hash bond in the Ethane structure. |
06:18 | Click on Add a hash bond. |
06:21 | Click on all the bonds. |
06:27 | Let us now save the file. |
06:30 | Click on Save the current file icon on the toolbar. |
06:34 | Save as dialog box opens. |
06:37 | Enter the file name as Formation of bond . |
06:41 | Click on Save button. |
06:44 | Let's summarise. |
06:46 | In this tutorial we have learnt to, |
06:49 | Add bonds to the existing bond |
06:52 | Orient the bonds |
06:54 | Add Stereochemical bonds |
06:56 | and Inverse wedge hashes. |
07:00 | As an assignment, Convert Propane to Propyne |
07:04 | Draw Propane and butane structures |
07:07 | Show the stereochemical bonds. |
07:11 | Your completed assignment should look like this. |
07:16 | Watch the video available at this URL http://spoken-tutorial.org /What_a_Spoken_Tutorial. |
07:19 | It summarizes the Spoken Tutorial project. |
07:23 | If you do not have good bandwidth, you can download and watch it. |
07:28 | The Spoken Tutorial Project Team: Conducts workshops using spoken tutorials. |
07:33 | Gives certificates to those who pass an online test. |
07:36 | For more details, please write to contact@spoken-tutorial.org. |
07:42 | Spoken Tutorial Project is a part of the Talk to a Teacher project. |
