WebJul 2, 2024 · In this video we introduce the concept of monomers and polymers using a few examples, as well as the important reactions of condensation and hydrolysis. WebFeb 12, 2024 · A monomer is a small molecule that reacts with a similar molecule to form a larger molecule. It is the smallest unit in a polymer, which is often a macromolecule with high molecular weight. Monomers are the building blocks for biological macromolecules such as DNA, RNA, proteins and carbohydrates. At the end of digestion, these polymers …

WebAnswer 1: When ethenol (CH (OH)=CH 2) is polymerised, the C-C double bond opens to produce a repeating unit of CH (OH)-CH 2. This gives the polymer poly (ethenol) Answer 2: To find the monomer, first the repeating unit should be deduced. Repeating units have only 2 carbons in the polymer main chain. Since the repeating unit is now found, it can ...
