| Column-A | Column-B |
| Nylon 6 | Natural Rubber |
| Vulcanized Rubber | Cross Linked |
| cis-1,4-polyisoprene | Caprolactam |
| Polychloroprene | Neoprene. |
Choose the correct answer from option given below
Solution:
a) Nylon 6 is synthesized from Caprolactam, hence a→III
b) Vulcanized Rubber involves cross-linking, hence b→II
c) cis–1,4–polyisoprene is the polymer form of Natural Rubber, hence c→I
d) Polychloroprene is commercially known as Neoprene, hence d→IV
Therefore, the correct matching is option (3).
What will be the equilibrium constant of the given reaction carried out in a \(5 \,L\) vessel and having equilibrium amounts of \(A_2\) and \(A\) as \(0.5\) mole and \(2 \times 10^{-6}\) mole respectively?
The reaction : \(A_2 \rightleftharpoons 2A\)

Cobalt chloride when dissolved in water forms pink colored complex $X$ which has octahedral geometry. This solution on treating with cone $HCl$ forms deep blue complex, $\underline{Y}$ which has a $\underline{Z}$ geometry $X, Y$ and $Z$, respectively, are
