(a) Nylon 6 (I) Natural Rubber
(b) Vulcanized Rubber (II) Cross Linked
(c) cis-1, 4-polyisoprene (III) Caprolactam
(d) Polychloroprene (IV) Neoprene

Choose the correct answer from options given below:

Multiple Choice Options

  • A a→III,b→II,c→I,d→IV\mathrm{a} \rightarrow \mathrm{III}, \mathrm{b} \rightarrow \mathrm{II}, \mathrm{c} \rightarrow \mathrm{I}, \mathrm{d} \rightarrow \mathrm{IV}
  • B a→II,b→III,c→IV,d→I\mathrm{a} \rightarrow \mathrm{II}, \mathrm{b} \rightarrow \mathrm{III}, \mathrm{c} \rightarrow \mathrm{IV}, \mathrm{d} \rightarrow \mathrm{I}
  • C a→IV,b→III,c→I,d→II\mathrm{a} \rightarrow \mathrm{IV}, \mathrm{b} \rightarrow \mathrm{III}, \mathrm{c} \rightarrow \mathrm{I}, \mathrm{d} \rightarrow \mathrm{II}
  • D a→III,b→IV,c→I,d→II\mathrm{a} \rightarrow \mathrm{III}, \mathrm{b} \rightarrow \mathrm{IV}, \mathrm{c} \rightarrow \mathrm{I}, \mathrm{d} \rightarrow \mathrm{II}

Step-by-Step Verified Solution

Nylon 6 is a synthetic polymer made from caprolactam, so it corresponds to Column A, option (c), which matches with Column B, option (I).

Vulcanized rubber is rubber that has been treated with sulfur or other additives to make it more durable, so it corresponds to Column A, option (b), which matches with Column B, option (II).

Cis-1,4-polyisoprene is a naturally occurring polymer found in natural rubber, so it corresponds to Column A, option (a), which matches with Column B, option (III).

Polychloroprene is a synthetic polymer used to make neoprene, a type of synthetic rubber, so it corresponds to Column A, option (d), which matches with Column B, option (IV).

Therefore, the correct matching is:

a→III,b→II,c→I,d→IV\mathrm{a} \rightarrow \mathrm{III}, \mathrm{b} \rightarrow \mathrm{II}, \mathrm{c} \rightarrow \mathrm{I}, \mathrm{d} \rightarrow \mathrm{IV}

Option A is the correct answer.
