Question

Match List I with List II. 

	List-I		List-II
A.		I.	Br2 in CS2
B.		II.	Na2CR2O7/H2SO4
C.		III.	Zn
D.		IV.	CHCl3/NaOH

Choose the correct answer from the options given below:

• A. A-IV, B-III, C-II, D-I
• B. A-IV, B-III, C-I, D-II
• C. A-II, B-III, C-I, D-IV
• D. A-IV, B-II, C-III, D-I

Answer 1

The Correct Option is A

To solve the problem, we need to match each chemical reaction (List I) with the appropriate reagent or process (List II). Let's analyze each option:

1. Option A:

   

   This reaction typically involves a formylation using a haloform reaction, which is characteristic of the reagent CHCl₃/NaOH.
2. Option B:

   

   Here, we see an oxidation of an alcohol to a ketone, which is commonly done using Zn as a reducing agent in some contexts.
3. Option C:

   

   This reaction looks like a typical oxidation that can be achieved with Na₂Cr₂O₇/H₂SO₄.
4. Option D:

   

   This substitution reaction with a halogen group is best known to involve Br₂ in CS₂.

By matching the images with the correct reagents, we confirm the pairs:

• A-IV: Reaction with CHCl₃/NaOH.
• B-III: Oxidation with Zn.
• C-II: Oxidation with Na₂Cr₂O₇/H₂SO₄.
• D-I: Bromination using Br₂ in CS₂.

Therefore, the correct answer is: A-IV, B-III, C-II, D-I.
