Q136 · CSIR NET Chemistry, June 2011
Paper: CSIR NET June 2011 · Subject: Physical Chemistry · Chapter: Polymer Chemistry · Topic: Polymer Chemistry – General · Marks: 2 · Difficulty: Medium
There are several types of mean molar masses for polymer and they are dependent on experimental methods like: (1) Osmometry (2) Light scattering (3) Sedimentation. Correct relation between mean molar masses and experimental method is:
(a)$\overline{M}_n \Rightarrow (3), \overline{M}_w \Rightarrow (2), \overline{M}_z \Rightarrow (1)$
(b)$\overline{M}_n \Rightarrow (2), \overline{M}_w \Rightarrow (3), \overline{M}_z \Rightarrow (1)$
(c)$\overline{M}_n \Rightarrow (1), \overline{M}_w \Rightarrow (2), \overline{M}_z \Rightarrow (3)$
(d)$\overline{M}_n \Rightarrow (1), \overline{M}_w \Rightarrow (3), \overline{M}_z \Rightarrow (2)$
