Total connectivity
Is the connectivity considered over all the heteroatoms.
Total Valence Connectivity
Is the valence connectivity considered over all the heteroatoms.
Vapor pressure
Is the pressure exerted by a vapor in equilibrium with its solid or liquid phase. Vapor pressure measures the con-
centration of solvent molecules in the gas phase.
Vapor pressure can be calculated using Raoult’s law. The formula to calculate vapor pressure is:
Water solubility
Is the maximum amount of a substance that can be dissolved in water at equilibrium at a given temperature and pres-
sure. Water solubility is measured in mg/L.
Wiener index
Provides measure of branching defined as:
Preferences
You can customize ChemDraw/Excel for the way you work.
To customize ChemDraw/Excel, go to ChemOffice>Preferences and select one or more options from the list below:
Double-click To Add a molecule- launches ChemDraw when you double-click a cell.
Ask Before Adding Molecule- prompts a message when you double-click a cell to add a molecule.
Align Structure-specifies how the structure is to be aligned in a cell. You can choose to reduce the column width,
row height or both.
Import Table- specifies whether to overwrite the table or to append records to the existing table.
Ask if the Record Import count Exceeds- a prompt appears when the table being imported contains more rec-
ords than the count number specified.
Ask Before Clearing Cells- a prompt appears when you try to delete the cell content in a ChemOffice worksheet
by either pressing DELETE or BACKSPACE.
Automatically generate structures while importing a table- Select this option to generate structure pictures for
each record while importing a table using the "Import Table" command. Disabling this option can speed up the
import process. Only structure and table data are imported and no pictures are generated. Select the structure cells
and use Show Picture to display the pictures.
