Question details

4. Please see the formula for the freely rotating model of the polymer below and answer the questions. r for a freely rotating chain with 2 different angles is: r-nP ( 1-cos 0) ( 1-cos 02)/ 1-cos θι cos θ.) The A, 02, angle is 98*; the O angle, 0,, is 132; -1.75 A What is the value of r/nl? How does this compare to the value for polyethylene PE, and why is different?
