If

{M_w}

is the weight average molecular weight and

{\bar M_n}

is the number of average molecular weight of a polymer, the poly dispersity index (PDI) of the polymer is given by

View answer and explanation

Correct option: B

\frac{{{{\bar M}_w}}}{{{M_n}}}

Option B (

\frac{{{{\bar M}_w}}}{{{M_n}}}

) is correct because the polydispersity index (PDI) is defined as the ratio of weight average molecular weight to number average molecular weight.
