POLYMERS Quiz-9
Dear Readers,
IIT JEE exam which consists of JEE Main and JEE Advanced is one of the most important entrance exams for engineering aspirants. The exam is held for candidates who are aspiring to pursue a career in the field of engineering and technical studies.
Chemistry is important because everything you do is chemistry! Even your body is made of chemicals. Chemical reactions occur when you breathe, eat, or just sit there reading. All matter is made of chemicals, so the importance of chemistry is that it's the study of everything..
Q1.The method of choice for determining the molecular weight of a polymer is::
Solution
option (a) Osmotic pressure method is best for the determination of molecular weight of polymers and proteins since O. P., through very small, is measurable. On the other hand, in other colligative properties (e.g., ∆T_b,∆T_f,∆p/p^0 methods), the difference is very small and cannot be measured. Moreover, in O.P. method, heating is not required, while in other methods, heating is required which changes the properties of polymer and proteins
