Question 1
Determine the end-to-end separation (direct distance between molecule ends), in Angstroms of a coiled PTFE molecule with a molecular weight of 692,484 g/mol, given that the tetrahedral bond angle is 109.5 degrees and the carbon-carbon bond length is 1.54 Angstroms. End-to-End distance (R): The polymer with the same C-C bonds can have different R values. Polymer chains in the same sample can have many interconverting conformations. Therefore, the average end-to-end distance (Contour length) is calculated.
Question 2
Question 3
Answer to question 1
Given:
Polymer – PTFE (Polytetrafluoroethylene).
Molecular weight of polymer – 692,484 g/mol.
Here,
d – the distance between two carbon atoms.
Therefore, the End-to-End distance of the coiled PTFE polymer is
