We know that we can use common names to represent functional groups when drawing chemical structures, so what are functional groups, and how can we use common names to mark functional group atoms in ChemDraw? We can take a look together.

1. Definition of functional group:

Functional groups are atoms or groups of atoms that determine the chemical properties of organic compounds. Common functional groups include alkenes, alcohols, phenols, ethers, aldehydes, ketones, etc. Organic chemical reactions mainly occur on functional groups, which play a decisive role in the properties of organic matter. -X, -OH, -CHO, -COOH, -NO2, -SO3H, -NH2, RCO-, these functional groups determine the properties of organic matter. Chemical properties of halogenated hydrocarbons, alcohols or phenols, aldehydes, carboxylic acids, nitro compounds or nitrite esters, sulfonic acid organic compounds, amines, and amides.

In chemistry, common names are allowed to represent functional groups, which are used for ChemDraw atom tags or part of atom tags. Common names have chemical meanings but not text. ChemDraw common names can define ChemDraw shortcut keys to facilitate more efficient use of ChemDraw software.

2. How to label functional group atoms with common names:

ChemDraw atomic tags can be implemented using common names. The method is:

1. Establish a chemical structure;

2. Double-click the atom with the "Key" tool or click the atom with the "Text" tool, and a text box will appear;

3. Enter a common name tag, for example: Me.

Note: The chemical meaning of chemical structures labeled with common names remains unchanged.

3. How to quickly choose a common name:

1. Position the atoms in the drawn structure;

2. Press the shortcut key "=", and a list of common names will appear;

3. Select a common name from the list and click the "OK" button.

4. How to delete common names:

1. Select the common name to be deleted from the common name list dialog box;

2. Click the Delete button in the common name list dialog box, and the common name will be permanently deleted.

Summary: The above is the definition of functional groups, the concept of common names of ChemDraw atom markers and how to use them. It would be very gratifying if it can help your learning process. More software tutorials are hereHuajun Software Park Information Tutorial Center! ! !
