Propylene (or propene in proper IUPAC nomenclature), H2C=CH-CH3, can be reacted by addition polymerization to form polypropylene (PP). The process is initiated with the radical, I*.

Choose the image above that properly indicated the location of the unpaired electron, *.

What is the degree of polymerization, n, of PP with a molecular weight of 3.091e5 g/mol?

what image?

degree of polymerization is like this

propylene is H2C=CH-CH3 so 3C and 6C
molec. weigth (12*3)+6 = 42 g/mol

n = 3.091*10^5 / 42 = 7359.52
