In the solvent hexane, the average end-to-end distance of a 7 kDa molecular weight poly(ethylene glycol) polymer chain is 3.65 nm and the average end-to-end distance of a 56 kDa molecular weight poly(ethylene glycol) polymer chain is 7.30 nm. By calculation, show whether hexane is a good, poor or theta solvent for poly(ethylene glycol).
