- Using the program Bondit
-
- Bondit is a program designed to provide practice for students
- taking introductory high school, Advanced Placement, or college
- level general chemistry. Organic compounds can also be done including
- some ring compounds. The intent is to provide the student with practice
- in drawing Lewis dot formulas that follow the octet rule. A
- 3-dimensional representation can also be seen after the structural
- formula has been completed. Molecules and structures can be created,
- saved to the clipboard, and then copied into any other Windows
- application.
- Two predesigned sets of compounds are included with the
- registered copy which can be used as classroom exercises. A text file
- is included with the registered version called ORGANIC.LAB which will
- provide the student with a number of organic compounds.
- Compounds up to 26 atoms in size can be created with the program.
- The unregistered version of the program can only do compounds
- containing H and O. The registered copy can do compounds
- containing any combination of the atoms listed on the left of the
- screen when the program is running. To obtain a registered copy
- of bondit see the file register.doc.
-
- Installing bondit on you hard drive.
-
- Start windows and place the disk with the bondit files in your
- disk drive. Click on File|Run in the upper left hand corner of program
- manager. The name of the program to be run is A:install. If the files
- are on directory C:\temp then enter c:\temp\install. The files
- will be installed onto your hard drive and a program group created for
- bondit including icons for some of the bondit files.
-
- Using bondit
-
- The goal of bondit is to draw an electron dot representation
- (Lewis formula) of molecules which follow the octet rule. To
- choose an atom click the appropriate symbol on the left of the
- screen. The atom chosen will appear on the right. The atom may
- be moved by placing the mouse cursor over it, clicking the left
- mouse button, and dragging the atom to the area desired. To bond
- one atom to another select a single atom by using the mouse and
- move it so that it is placed above the atom with which you wish to
- bond. Releasing the mouse button will bond the two atoms together
- if possible. An atom cannot exceed 8 electrons (a single bond
- counts as 2) except hydrogen which cannot exceed 2 electrons.
- Multiple bonds may be made by clicking the right mouse button over
- the existing bond you want to make a multiple bond. If there are
- too many or not enough electrons for bonding a multiple bond will
- not form. Cations and anions can be made by choosing the Edit|Add
- Electron or Edit|Subtract Electron option.
- Click on 3-D model to see a three-dimensional representation
- of a completed molecule. Pressing the "End" key will accomplish
- the same thing. The molecule may be rotated using the arrow keys
- or moved using the shift and arrow keys. Press "Home" to return.
-
- Molecule Menu Items:
-
- New
- This menu item will start a new molecule. You will be asked
- if you want to save the molecule you were working on previously.
-
- Open
- This menu item will open a previously saved molecule. Use the
- mouse or keyboard to select the file of interest. Files can also
- be deleted by choosing delete after selecting the desired file.
-
- Save
- To save a molecule choose this option. If the molecule
- already has a name the new state of the molecule will replace the
- former state. If the molecule does not have a name you will be
- asked for one. Use a single word with no spaces of 8 letters or
- less.
-
- SaveAs
- To save a molecule under a different name while retaining the
- molecule with the former name use this option. You will be asked
- for a filename. Use a single word with no spaces of 8 letters or
- less.
-
- Print
- This command will print the current contents of the presently
- displayed window. Be patient as this process can be slow on some
- computers.
-
- Exit
- This command will terminate the program.
-
- Edit Menu
-
- Undo
- Choose this menu item to return to the state of the molecule
- before your previous procedure.
-
- Add Electron
- To add an electron to an atom choose this menu item and then
- click the right mouse button on the atom which is to gain the
- electron.
-
- Subtract Electron
- To subtract an electron from an atom choose this menu item and
- then click the right mouse button on the atom which is to lose the
- electron.
-
- Abbreviate H's
- Occasionally you may wish to abbreviate a molecule so
- that you may bond other atoms. To do so click on this menu item.
- All H atoms will be abbreviated.
-
- Copy to Clipboard
- To copy a molecule or structure to the clipboard choose
- Edit|Copy to Clipboard when viewing the molecule or Copy to
- Clipboard if viewing the structure. The molecule or structure
- will be copied to the clipboard. To transfer the molecule or
- structure to another application start the application and choose
- Edit|Paste. The molecule or structure will be copied to your
- application and you can change it as you would any object added.
-
- Practice Menu
- Click on Start Lab or Organic Chemistry to do a series of
- preloaded molecules. A new menu bar will appear. To start the
- same molecule again choose the Repeat menu item. To go on to the
- next molecule click on the Next menu item. A completed molecule
- may be seen in three-dimensions by clicking on View|3-D model.
- You may Quit at any time by choosing Practice|Quit (returns to the
- regular program) or by choosing Molecules|Exit (terminates the
- program). The Practice menu will function only with the registered
- version.
