Question

Please explain the science needed to analyse the environmental issues concerning Molecular geometry.

Answer 1

The question is not very clear, and therefore I assume that environmental aspects to which you refer, is the chemical environment as an important element in the molecular geometry. The molecular geometry is defined by the electronic nature of atoms that make up this molecule. Each central atom will have a more stable conformation and is what defines its geometry, or order in space.

When a molecule is in an alterative chemical environment, they can lose their center of symmetry modifying their bond angles, and therefore its molecular conformation is altered. The repulsion caused by adjacent species, tend to affect distances and angles intramolecular bond, causing a geometric distortion of the molecule.

Other environmental aspects such as heat, radiation, etc., are causes of distortion in the molecular geometry, because they have a direct effect on the matter.

although is spoken of changes in geometry, in general, each molecule is described by a unique geometry although this may be distorted by external sources. when we talk about the geometry of the water, it is said that this is angular; the sp3 carbons have tetrahedral geometry, other organometallic compounds such as flat can be square, octahedral, etc.

All molecular conformations are symmetrical and for this reason we talk about geometry, and this depending on the substituents surrounding the central atom (steric effect, charges, electronegativity, valence), and the nature of this.

Please if you need other approach, leave me a note for help you.
