introduction to molecular geometry
Having a hard time in organic chemistry? With all those formulas, atoms, calculations or whatsoever, I'm sure you're having a hard time. But I know that you can make it through.
Another hard subject that we've been studying is Geometry. We usually learn this from our mathematics class, encountering angles, formulas, and geometrical figures that could sometimes make us dizzy.
We are able to understand the different subjects separately; one from science and one from mathematics. But what if we combine Geometry and Chemistry in one lesson? Quite disturbing right? It sounds hard at first but I know you're equipped with ample knowledge for this lesson.
One topic that applies the principles of Geometry to Chemistry is what we call Molecular Geometry.
Molecules, by definition, are most often held together with covalent bonds involving single, double, and/or triple bonds, where a "bond" is a shared pair of electrons
Molecular geometry is the three-dimensional arrangement of the atoms that constitute a molecule. It determines several properties of a substance including its reactivity, polarity, phase of matter, color, magnetism, and biological activity. The angles between bonds that an atom forms depend only weakly on the rest of molecule, i.e. they can be understood as approximately local and hence transferable properties.
Molecular geometries can be specified in terms of bond lengths, bond angles and torsional angles. The bond length is defined to be the average distance between the centers of two atoms bonded together in any given molecule. A bond angle is the angle formed between three atoms across at least two bonds. For four atoms bonded together in a chain, the torsional angle is the angle between the plane formed by the first three atoms and the plane formed by the last three atoms.
That is all for my introduction of Molecular Geometry. Hope your brain didn't explode.
