Hey there!
Answer to your query is ⇒
Molecular models are physical devices that are used for a better visualisation and perception of three-dimensional shapes of organic molecules.
These are made of wood, plastic or metal and are commercially available.
Commonly three types of molecular models are used:
(1) Framework model
(2) Ball-and-stick model
(3) Space filling model.
In the framework model only the bonds connecting the atoms of a molecule and not the atoms themselves are shown. This model emphasizes the pattern of bonds of a molecule while ignoring the size of atoms.
In the ball-and-stick model, both the atoms and the bonds are shown. Balls represent atoms and the stick denotes a bond.Compounds containing C=C (e.g, ethene) can best be represented by using springs in place of sticks. These models are referred to as balland-spring model.
The space-filling model emphasises the relative size of each atombased on its van der Waals radius. Bonds are not shown in this model. It conveys the volume occupied by each atom in themolecule.
In addition to these models, computer graphics can also be used formolecular modelling.
