How to Sketch a Molecule from Scratch: Part-1

It is often necessary in various scientific disciplines to prepare sketches of molecules for project reports, research papers and teaching assignments, etc. Drawing a sketch also helps in developing the concepts in science, for example, the bonding patter in organic molecules, their valencies, etc.
Educators and researchers regularly use sketches in their daily work. With the development of computing computer based sketching has become more  common and more and more people are using computers for everything for drug design, manufacturing and publications of results.
Several tools are available for sketching. Here, we will see how small molecules can be drawn using an exciting and free software ‘ACDChem Sketch’ from ACD Labs.
Lets begin by drawing a simple molecule ‘Indole’. The pictures below are self explaining.

You can build a larger molecule by adding side chains at the desired positions on the main Indole ring. The method is shown below.

Apart from building simpler molecule like indole, ACD ChemSketch is also capable of building sketches of complicated molecules like complex alkaloids.
ACD ChemSketch also contains loads of structure templates ranging from complex alkaloids to active groups of small molecules like ring systems and table of radicals.
Some more screenshots are shown below.

If you wish to draw more complex molecules, you can do so with the help of templates. ACDChemSketch contains templates of Alkaloids, Aromatic rings, Carbohydrates, etc. Template window can be accessed from Templates window.

A useful template for young science students is the Lab Kit template which includes various glassware commonly used in a chemical laboratory.
The students can learn the names of various types of glassware and their shapes. It’s a good tool for writing reports in chemistry, biochemistry, etc.
