The number average molelcular mass and mass average molecular mass of a polymer are respectively 30,000 and 40,000 . The poly dispersity index of the polymer is : lt1 gt 1 1 0

A

lt1

B

gt 1

C

1

D

0

Text Solution

Verified by Experts

The correct Answer is:
B
Pdi = ` (overset(-)M_w)/(overset(-)M_n) = (40,000)/(30,000)`
So , the value is more than 1.
