Relation belween number of average molecular mass `(overline(M)_(n))` and weight of average molecular mass `(overline(M)_(w))` of synthetid polymers isA. `overline(M)_(n) lt overline(M)_(w)`B. `overline(M)_(n) gt overline(M)_(w)`C. `overline(M)_(n)overline(M)_(w)`D. `overline(M)_(n)gt M_(w)`

Answer» Correct Answer - A
Polydispersity index (PDI) of polymer=`overline(M)_(w)/overline(M)_(n)`
For natural polymers, PDI = 1, i.e. `overline(M)_(w) = overline(M)_(n)`
For synthetic polymers PDI = 1, i.e. `overline(M)_(w) gt overline(M)_(n)`
