The similarities between crystal of molecules and polymers are;
- Both are are composed of regular repeating units of molecules
- Both can be arranged in a definite pattern to give a solid material
Differences between a crystal of molecules and a polymer are;
- Polymers result from long chains of molecules while crystal of molecules results from the aggregation of a fewer number of molecules.
- molecules polymers are held together by chemical bonds while molecules in crystal of molecules are held together by weak inter-molecular forces.
Many molecules occurs as crystals. These crystals of molecules have a well defined shape and are composed of a regular repeating unit of molecules not held together by chemical bonds.
Polymers are formed from small molecules called monomers which are arranged in a regular repeating manner to form macro-molecular structures which sometimes have a high tensile strength.
