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

Let's match each item from List-I with the correct statement from List-II:
(A) Ambient nucleophiles:
Ambient nucleophiles refer to molecules or ions that are nucleophilic (able to donate electrons) in nature. They are often involved in nucleophilic substitution reactions. This corresponds to cyanides and nitriles (III), which are typical examples of nucleophilic compounds.
(B) Plane polarized light:
Plane polarized light refers to light waves oscillating in only one plane. This property is related to optical activity, which can be detected using a Nicol Prism (IV), a device used to produce plane polarized light.
(C) Superimposable mirror image:
A superimposable mirror image occurs when an object can be overlapped onto its mirror image, indicating that the object is symmetrical (I). For example, a symmetrical molecule or object has mirror images that can be perfectly superimposed.
(D) $\beta$-elimination reaction:
The $\beta$-elimination reaction is a reaction where elements or groups are removed from adjacent carbon atoms, often leading to the formation of alkenes. The Saytzeff rule (II) is applied in these reactions, predicting the formation of the more substituted product.
Conclusion:
Thus, the correct matching is:
- (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: \[ \boxed{\text{The correct matching is (A) - (III), (B) - (IV), (C) - (I), (D) - (II).}} \]
