The polydispersity index of natural polymers is _________(a) 0(b) 1.2I

1.	The polydispersity index of natural polymers is _________(a) 0(b) 1.2I had been asked this question during a job interview.This interesting question is from Molecular Mass of Polymers topic in section Polymers of Chemistry – Class 12
Answer» Right choice is (C) 1 Easy EXPLANATION: Natural polymers generally have chains of identical lengths and have definite molecular masses (Mw=Mn). This makes them more HOMOGENEOUS and monodisperse, with a PDI of approximately 1.
