![]() Share the cost with some friends, keep it in good condition and don't lose any bits, and resell it via eBay or Amazon at the end of your course.Īlternatively, get hold of some coloured Plasticene (or other children's modelling clay) and some used matches and make your own. Google molymod to find a supplier and more about them, or search for molymod on Amazon. An introductory organic set is more than adequate. The models made by Molymod are both cheap and easy to use. If your school or college hasn't given you the opportunity to play around with molecular models in the early stages of your organic chemistry course, you might consider getting hold of a cheap set. Note: This is all much easier to understand if you have actually got some models to play with. One structure is in reality a simple rotation of the other one. But these two structures are actually exactly the same. The chlorines could be opposite each other or at right angles to each other. You might think that there were two different ways of arranging these atoms if you drew a displayed formula. This mismatch between what you draw and what the molecule actually looks like can lead to problems if you aren't careful.įor example, consider the simple molecule with the molecular formula CH 2Cl 2. Notice that the way the methane is drawn bears no resemblance to the actual shape of the molecule. You need to remember that each line represents a pair of shared electrons.įor example, this is a model of methane together with its displayed formula: There are various ways of drawing this and you will need to be familiar with all of them.Ī displayed formula shows all the bonds in the molecule as individual lines. In cases like this, the bonding in the organic molecule isn't important.Ī structural formula shows how the various atoms are bonded. About the only place where you might come across them is in equations for the combustion of simple hydrocarbons, for example: Molecular formulae are very rarely used in organic chemistry, because they don't give any useful information about the bonding in the molecule. Lectures include the entire process which also involves downloading and installation of these software(s).Īt end of course candidate will be able to use these open-source software’s independently for their work.This page explains the various ways that organic molecules can be represented on paper or on screen - including molecular formulae, and various forms of structural formulae.Ī molecular formula simply counts the numbers of each sort of atom present in the molecule, but tells you nothing about the way they are joined together.įor example, the molecular formula of butane is C 4H 10, and the molecular formula of ethanol is C 2H 6O. Theory and practical sessions for better understanding. ![]() Learning outcomes: After successful completion of this module candidate will be able to study three dimensional properties of molecules which are highly useful in prediction of their chemical/ physical properties and can be applied in advanced research work. Learning outcomes: After successful completion of this module candidate will be able to use ACD ChemSketch for generation and processing of simple and complex chemical structures.ģD Viewer software: Introduction, download and installation process, 3D structures of molecules, various 3D structure models, conversion of 2D structure into 3D structure, File extensions, Cartesian coordinates, Dihedral angles, To be able to generate IUPAC names, retrieve information about physical properties, compute 3D geometrical properties and using it to create reports in MS Word.ĪCD ChemSketch software: Introduction, download and installation process, Drawing various chemical structures (acyclic, cyclic, polycyclic, heterocyclic), name generation from structures, conversion of name of molecule into its structure, calculation of physical properties such as density, molecular weight, molecular formula, refractive index from structural formula, bond angles, bond lengths, dihedral angles, etc. To be able to write complex reaction schemes, reaction mechanisms, use different templates, reaction symbols and arrows, smartly and efficiently. This course is aimed at imparting skills on use of structure drawing tools that are essential for student or researcher involved in the area of chemistry.Īfter successful completion of this course, the participants will be able to use these software(s) for drawing 2D and 3D (dimensional) chemical structures.
