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 ...
