Molecular geometry helps in determining the polarity, reactivity, phase of matter, color, magnetism, as well as the biological activity.
Molecular geometry is used to determine the shapes of molecules.
The shape of a molecule helps to determine its properties.
For example, carbon dioxide is a linear molecule. This means that CO2
molecules are generally non-polar and will not be very soluble in water which is a polar solvent.
Other molecules have different shapes. Water molecules have a bent structure. This is one of the reason why water molecules are polar and have some properties such as cohesion, surface tension and also hydrogen bonding.
Understanding molecular geometry also helps scientist to understand the shapes of more complex molecules such as proteins and also the DNA. The shapes of these molecules play incredibly important roles in determining the jobs performed by these molecules in our bodies.
