The following are the $Q$ and $e$ values for monomers $A,B,C,$ and $D$ :

a$.$ The following pairs of monomers are subjected to copolymerization reactions;

i$.$ A and B

ii$.$ C and D

Determine the reactivity ratio for each monomer based on the pairs.

Based on the reactivity ratios, which of these two copolymerization reactions

above will most likely result in an alternating polymer?

b$.$ Equimolar amounts of A and $B$ monomers are reacted to form a copolymer, at a

conversion $(x)$ of $0\mathrm{.}25,$ what is $F_A$ and $($:$F_A$:$)?$
