Molecular drawing programs are mostly used to create simple, two-dimensional illustrations for research, lectures, academic publications and similar purposes. The graphic representation of molecular structures is a fundamental language for describing physical reality, on the atomic level, and to accurately represent these images with high precision on a two-dimensional surface. It is an incredibly powerful tool for the process of understanding the nature of the molecule. ChemDraw 9.0, is a great molecular drawing program chalk to draw molecular structures, formulas, mechanisms and reaction pathways. Suddenly, it is possible for almost anyone to electronically produce these important two-dimensional images. ChemDraw has continued to develop in both breadth & depth over the last 20 years, and ChemDraw 9.0 offers an incredibly powerful package that continues to maintain itself as the chemical structure drawing standard
