Which pair of starting materials is needed to make Pentex^TM polymer, whose structure fragment is shown below?

Question

Quizplus · Accepted Answer

The structure fragment contains a pentene unit (Pent), a styrene unit (S1), a urethane unit (U1), a trimethylsilyl unit (-TMS1), and a propyl unit (P1). These units can be found in the molecule with the starting materials 11ec7f77_fcd2_501e_a1cf_bbd24fa38736_TB34225555_11, which contains pentene, styrene, propyl, and isocyanate functional groups. The isocyanate group can react with a hydroxyl group from a silanol compound (-SiOH) to form the urethane unit, and the trimethylsilyl group can be introduced as a protecting group for the hydroxyl groups during the polymerization process. Therefore, choice C is the best option for the starting materials needed to make Pentex^TM polymer.
