Just select the eraser tool and click on the atom or bond that you wish to erase. To add a functional group, for example, OH, select the text tool and click on the atom that you want to change to that group.
How do you shorten a bond in ChemDraw?
To suppress fixed lengths and fixed angles, press and hold the ALT key as you drag the bond.
How do you clean up structure in ChemDraw?
Select the structure or part of the structure you want to clean up with a selection tool. 2. From the Structure menu, choose Structure CleanUp. NOTE: Structure CleanUp does not position molecules relative to other objects.
How do you increase pages in Chem?
To change the document size: On the File menu, select Document Settings. On the Layout tab, select Document Type “Pages” Under “Document Size”, enter a number of pages for height and width.
How do you fix bond length in ChemDraw?
To draw a bond, choose the solid bond tool from the Main toolbar on the left. Fixed bond length -‐ Fixed bond angle -‐ Object>Fixed Lengths and/or Fixed Angles and if a check mark is next to the Fixed length and/ or Fixed Angles command, the bond in the structure will be of a default length and/or bond angle.
How do you draw a coordination bond in ChemDraw?
Click to select the end (i.e. the terminal atom) of the coordination bond in one structure, and then shift+click to select the end of the coordination bond in the second structure. On the Object menu, click Join. The two structures are joined so that they share an atom.
How do you hide hydrogens in ChemDraw?
Then select the Object Settings command from the Object menu to pop up the dialog box shown in the figure below, click Atom Labels and check the Hide Implicit Hydrogens check box at the bottom of the dialog box, and finally click the OK button.
What is chem Finder?
ChemFinder for Office lets you search for chemical structures in data sources such as documents and databases. It. is installed when you install ChemOffice Professional. You can browse through these types of sources: Microsoft Word documents.
Can ChemDraw predict pKa?
Values for pKa can be predicted or it can be looked up: ChemDraw’s “Chemical Properties” window looks up pKa for selected substances.
How do you draw a triple bond in ChemDraw?
There are three ways to draw a triple bond: Draw a bond using the Triple Bond tool. Using the Solid, Dashed, or Bold Bond tool, drag from one end of an existing double bond to the other end. Using any bond, or selection tool, point to an existing bond and type ‘3’ on your keyboard.
How do you type symbols in ChemDraw?
Go to chem draw, click the A in the left tab or insert text option, right click in the box, go to font and choose symbol. Now hit caps lock and press D. You will have the Δ. Symbol options can be used to add all types of chemical entities.
How do you open a chem?
In Chem3D, choose File | Open… to open the file. You may remember in ChemSketch that you could transform your 2D drawing in the drawing window. The program “cleaned” the bond lengths and angles to more “normal” values. You can do the same in the Chem3D window.
What does Ctrl G do in ChemDraw?
ChemDraw Shortcuts File Commands Command+L toggle fixed lengths scale Command+E toggle fixed angles rotate Command+G group selected objects flip horizontal Shift+Command+G ungroup objects rotate 180° horizontal.
Is Chem3D free?
An alternative for Mac users As you cannot download Chem3D to a Mac, this free software from ChemAxon may be a useful alternative: MarvinSketch.
What can ChemDraw do?
ChemDraw Professional is a drawing tool that allows users to draw chemical structures and reactions as well as biological objects and pathways. Users can also use it to predict properties and spectra, convert chemical structures to IUPAC names, view 3D structures, etc.
How do you make smiles in ChemDraw?
SMILES String – CAS Draw In ChemDraw, draw the structure and then Select All. In the ChemDraw Edit menu, go to Copy As, and then select SMILES or use the shortcut Alt+Ctrl+C.
How do you add text in Chem?
Adding atom labels Select the text tool from the tools palette. With the text tool selected, move to the end of an existing bond. When you are pointing to the end of the bond, a black square will appear. Press and release the mouse button without moving the mouse. A text editing box will appear.
How do you add hydrogens to ChemDraw?
To view all hydrogens explicitly displayed as atoms with bonds to neighbors, chose Structure > Add > Add Explicit Hydrogens. The Structure > Remove > Remove Explicit Hydrogens will return to the previous display mode. You can use these functions locally, that is, only apply it to the selected structures.
How do you draw a radical in ChemDraw?
Radical Hold down the mouse button over the Chemical Symbols tool and drag to select the radical from the palette. Point to the atom where you want the radical symbol to appear. Click to draw the symbol.
How do you hide carbons in ChemSketch?
With a ChemSketch structure displayed: Switch to Structure mode. Click the Select/Move button. Double-click the CH3 group to be hidden. Click the Atom tab in the Properties dialog box that appears. Click on the small C icon (under the box with the CH3 label in it).
What are implied hydrogens?
Implicit / Explicit / Query Hydrogens. The Hydrogen atoms are included in the molecule implicitly, explicitly or both. The implicit hydrogen count is calculated from the valence of the atom. The implicit hydrogens can be converted to explicit ones and vice versa.
What is a bold bond?
Under the program, bonds are issued that finance both infrastructure improvements and development impact fees for residential and non-residential projects.
How do you cite ChemSpider?
You can cite a ChemSpider compound record using the permalink based on the ChemSpider ID, e.g. http://www.chemspider.com/Chemical-Structure.1906.html.
