Question

Match List-I with List-II \[ \begin{array}{|l|l|} \hline \textbf{List-I} & \textbf{List-II} \\ \hline (A) \; \text{Ambient nucleophiles} & (I) \; \text{Symmetrical object} \\ \hline (B) \; \text{Plane polarized light} & (II) \; \text{Saytzeff rule} \\ \hline (C) \; \text{Superimposable mirror image} & (III) \; \text{Cyanides and nitriles} \\ \hline (D) \; \beta\text{-elimination reaction} & (IV) \; \text{Nicol Prism} \\ \hline \end{array} \]

• (A) - (III), (B) - (IV), (C) - (I), (D) - (II)
• (A) - (I), (B) - (III), (C) - (II), (D) - (IV)
• (A) - (B), (B) - (III), (C) - (I), (D) - (IV)
• (A) - (III), (B) - (IV), (C) - (I), (D) - (II)

Hint:

The Nicol Prism is used in optical devices to polarize light, and the Saytzeff rule applies to $\beta$-elimination reactions, predicting the most substituted product.

Answer 1

The Correct Option is A

To associate each item from List-I with its corresponding statement in List-II, consider the following definitions:
(A) Ambient nucleophiles: These are electron-donating molecules or ions, common in nucleophilic substitution. Cyanides and nitriles (III) exemplify such nucleophilic compounds.
(B) Plane polarized light: This light oscillates in a single plane. Its detection relates to optical activity, observable with a Nicol Prism (IV), which generates plane polarized light.
(C) Superimposable mirror image: This occurs when an object and its mirror image can be perfectly overlaid, indicating symmetry (I). Symmetrical objects exhibit this property.
(D) $\beta$-elimination reaction: In this reaction, groups are removed from adjacent carbon atoms, typically forming alkenes. The Saytzeff rule (II) guides the prediction of the more substituted product in such reactions.
Conclusion: The established pairings are:
- (A) Ambient nucleophiles → (III) Cyanides and nitriles
- (B) Plane polarized light → (IV) Nicol Prism
- (C) Superimposable mirror image → (I) Symmetrical object
- (D) $\beta$-elimination reaction → (II) Saytzeff rule
Final Answer: \[\boxed{\text{The correct matching is (A) - (III), (B) - (IV), (C) - (I), (D) - (II).}}\]
