FAQs on Molecular Mass of Polymers Video Lecture - Chemistry for JEE Main & Advanced

1. What is molecular mass?
Ans. Molecular mass refers to the sum of the atomic masses of all the atoms in a molecule. It is typically expressed in atomic mass units (amu) and is used to determine the mass of a molecule. The molecular mass is important in various chemical calculations, such as stoichiometry and determining the concentration of a solution.
2. How is molecular mass calculated?
Ans. The molecular mass of a polymer is calculated by adding up the atomic masses of all the atoms present in its chemical formula. Each element's atomic mass can be found on the periodic table, and it is multiplied by the number of atoms of that element in the molecule. The molecular mass is the sum of these individual masses.
3. Why is molecular mass important in polymer chemistry?
Ans. Molecular mass is crucial in polymer chemistry as it determines various properties of polymers. It affects the physical properties, such as the melting point, boiling point, and density, as well as the chemical properties of the polymer. The molecular mass also influences the polymer's mechanical properties, such as its strength, flexibility, and durability.
4. How does molecular mass affect the behavior of polymers?
Ans. The molecular mass of a polymer affects its behavior in several ways. Higher molecular mass polymers tend to have higher melting points and boiling points, as well as higher viscosities. They also exhibit stronger intermolecular forces, leading to increased strength and stiffness. On the other hand, lower molecular mass polymers are often more flexible and have lower melting points.
5. Can molecular mass be used to determine the polymer's structure?
Ans. While molecular mass provides information about the overall size and weight of a polymer, it does not directly reveal its specific structure. Molecular mass alone cannot determine the arrangement of monomer units or the presence of branches or cross-links in the polymer chain. Additional characterization techniques, such as spectroscopy or chromatography, are required to determine the detailed structure of polymers.
