Due to social distancing in the past week, Dr. Sumerlin finally got to chase one of his childhood dreams: making polysulfones in his garage. He reacted hydroquinone in the presence of a base with various bis-phenylsulfones and found that some would polymerize much faster than others.  Rank the following bis-phenylsulfones according to their expected reaction rate with hydroquinone, starting with the fastest.

The polymerization of the monomer shown below yields a very important commercial polymer. The success of this process relies on the rate differences of steps A vs. B and C vs. D.  Indicate which steps are faster.

Interfacial polymerization of a diacid chloride and a diamine is a [heterogeneous] polymerization technique for the preparation of [polyamides]. Acidic pH in the aqueous phase will [decrease] the polymerization rate.

What is the value for Mo (average structural unit molecular weight) used in the calculation above? Your answer has to be correct within +/- 5 g/mol.

Methylation (i.e., substitution with a -CH3 group) on which position would have the greater effect on the melting point of  poly(ε-caprolactam)?
