Subject: Physical Chemistry · Chapter: Polymer Chemistry · Topic: Polymer Chemistry – General · Exam: NET JUNE 2011 · 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)$\overline{\mathrm{M}}_{\mathrm{n}} \Rightarrow(3), \overline{\mathrm{M}}_{\mathrm{w}} \Rightarrow(2), \overline{\mathrm{M}}_{\mathrm{z}} \Rightarrow(1)$
(b)$\overline{\mathrm{M}}_{\mathrm{n}} \Rightarrow(2), \overline{\mathrm{M}}_{\mathrm{w}} \Rightarrow(3), \overline{\mathrm{M}}_{\mathrm{z}} \Rightarrow(1)$
(c)$\overline{\mathrm{M}}_{\mathrm{n}} \Rightarrow(1), \overline{\mathrm{M}}_{\mathrm{w}} \Rightarrow(2), \overline{\mathrm{M}}_{\mathrm{z}} \Rightarrow(3)$
(d)$\overline{\mathrm{M}}_{\mathrm{n}} \Rightarrow(1), \overline{\mathrm{M}}_{\mathrm{w}} \Rightarrow(3), \overline{\mathrm{M}}_{\mathrm{z}} \Rightarrow(2)$
