Question 1.

Which of the given polymers would be best prepared using cationic polymerization?

An illustration depicts four chemical structures of polymers.The first structure labeled Roman numeral 1 has two linearly arranged carbon atoms single bonded to each other. From right to left, the C 1 is single bonded to an oxygen atom, O, a hydrogen atom, H, and has an open bond. The oxygen atom is further single bonded to a carbon atom which is then double bonded to another oxygen atom and single bonded to a methyl group, C H 3. The C 2 is single bonded to two hydrogen atoms, and has an open bond. The structure is enclosed within a square bracket. An alphabet n is at the base of the square bracket. The open bond at C 1 and C 2 extends outside the square bracket.The second structure labeled Roman numeral 2 has two linearly arranged carbon atoms single bonded to each other. From right to left, the C 1 is single bonded to Nitrogen dioxide, N O 2, hydrogen atom, H, and has an open bond. The C 2 is single bonded to two hydrogen atoms, and has an open bond. The structure is enclosed within a square bracket. An alphabet n is at the base of the square bracket. The open bond at C 1 and C 2 extends outside the square bracket.The third structure labeled Roman numeral 3 has two linearly arranged carbon atoms single bonded to each other. From right to left, the C 1 is single bonded to a carbon atom, which is further bonded to a methyl group and double bonded to an oxygen atom. C 1 is also single bonded to a hydrogen atom and has an open bond. The C 2 is single bonded to a hydrogen atom, H, a methyl group, C H 3, and has an open bond. The structure is enclosed within a square bracket. An alphabet n is at the base of the square bracket. The open bond at C 1 and C 2 extends outside the square bracket.The fourth structure labeled Roman numeral 4 has two linearly arranged carbon atoms single bonded to each other. From right to left, the C 1 is single bonded to two fluorine atoms and has an open bond. The C 2 is single bonded to two hydrogen atoms, H and has an open bond. The structure is enclosed within a square bracket. An alphabet n is at the base of the square bracket. The open bond at C 1 and C 2 extends outside the square bracket.
