Predict the order of polymer molecular weight obtainable (highest to lowest) by the free radical solution polymerization of styrene in benzene, toluene, ethylbenzene, i-propylbenzene, and t-butylbenzene
Predict that it was dissolved in HCl then mixed into the diethyl ether because diethyl ether is a base and since the benzoate contains an amine group they would remain unreactive with one another.
