Introduction about ACD/ChemSketch



ACD/ChemSketch is a software that make the works of drawing structures of chemical structures of atoms and compounds easier. It consist a lot of useful buttons.


As a basic, we learn to draw chemical bonds (single, double and triple) and atoms using the buttons in the Structure toolbar and general toolbar. For instance, we are being familiarize with Draw Normal tool, Set Bond Vertically button, Undo and Redo buttons, Polymers button and others buttons’ functions. Apart from that, we learn about the cleaning process and also how to flip and make the structures more organized using Clean Structure buttons.


From the basic, we continue to learn how to draw more complex structures using ACD/Chemsketch. We use Table of Radicals to choose the respective structure such as octahydro-1H-indene structure. Furthermore, Markush Bond tools is used to make the selected atom, for example Br, to appear connected to any of the carbon atoms in cyclic structures. ACD/ChemSketch also allows us to generate stereo descriptors for chiral and pseudo chiral centers, and for a double-bond configuration.In addition, using this ACD/ChemSketch, we also can draw the set up of apparatus as required for experiments.


In conclusion, ACD/ChemSketch is a useful software program for students, lecturers, chemists, scientists and everyone who related to chemistry and biology studies for reports and presentations.
