With the 444PCS organic chemistry model kit,you can build models such as:alkanes,alkenes,alkynes,alky halides,alcohols,ethers,aldehydes,ketones,carboxylic acids,nitriles,amines,esters,aromatic compounds,heterocycliccompounds and more.
1.Ball-and-stick models
Ball-and-stick models use spheres to represent atoms and sticks to represent chemical bonds. The advantage of ball-and-stick models is that they show the correct angles between the bonds. However, the relative sizes of the spheres do not always match the relative sizes of the atoms they represent.
2.Space-filling models
In real molecules, however, the atoms touch each other. Both of these disadvantages are overcome with space-filling models. in which the spheres are drawn to scale and are next to one another as atoms are in real molecules. The disadvantage of space-filling models is that the bond angles between atoms may be hard to see.
3.Fullerene models
Fullerene is the third isomorphic body found in elemental carbon. The structure of fullerene is similar to the representative work of architect Fuller, so it is called fullerene.
