Write down the molecular structure of repeating unit of PEO. if the peo chain follows freely rotating chain find out the relation between radius of gyration and molecular weight of the chain. What is the characteristic ratio of this chain $?$ The chain of C$-$C bond itwrite down the molecular structure of repeating unit of peo. if the peo chain follows freely rotating chain find out the relation between radius of gyration and molecular weight of the chain. What is the characteristic ratio of this chain $?$ What is the Kuhn length and statistical segment length of this chain $?$ The length of C$-$C bond and C$-$O bond is $0\mathrm{.}154$ and $0\mathrm{.}146$ respectively
