The number average molar mass and mass average molar mass of a polymer are respectively 30,000 and 40,000. The polydispersity index of the polymer is

A

`lt1`

B

`gt1`

C

0

D

`-1`

Text Solution

Verified by Experts

The correct Answer is:
B
olydispersity index (P.D.I.)
`="Mass average molar mass"/"Number average molar mass"=M_w/M_n = (40,000)/(30,000)=1.3 gt 1`
