Answer:

<u><em>Structure:</em></u>

<em>Differences-  </em>A polymer is a collection of a large number of molecules whereas a monomer is a single molecule.

A monomer is a single molecule, which has the ability to chemically bond with other monomers in a long chain. A polymer is a chain that is made when monomers bind with other monomers.

<em>Similarities-</em>  They are both molecules

<u><em>Properties:</em></u>

<em> Differences- </em>Monomers have polyfunctionality, which is the capacity to form chemical bonds to at least two other monomer molecules. Polymers are chemically unreactive, solids at room temperature, malleable, tough, and are electrical insulators.

<em>Similarities- </em>They both makeup larger forms of matter.

<u><em>Intermolecular Forces</em></u>

<em>Differences: </em>Polymers are held together by covalent bonds, hydrogen bonds, and dispersion bonds. Monomers are <u><em>only</em></u> held together by hydrogen bonds.

<em>Similarities: </em>They can both be bonded together by hydrogen bonds.
