Question

Match List-I with List-II

Choose the correct answer from the options given below:

 

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

Answer 1

The Correct Option is A

To solve this question, we need to match chemical reactions in List-I with their corresponding names in List-II. Let's analyze each reaction one by one: 

1. Reaction (A): Benzoyl chloride (C₆H₅COCl) is being reduced to benzaldehyde (C₆H₅CHO) using H₂ over palladium-barium sulfate (Pd-BaSO₄). This is known as the Rosenmund reaction. This matches with List-II (IV).
2. Reaction (B): The conversion of a nitrile to an aldehyde using SnCl₂ and HCl followed by hydrolysis is the characteristic of the Stephen reaction. This matches with List-II (III).
3. Reaction (C): Oxidation of a methyl group to an aldehyde using CrO₂Cl₂ (chromyl chloride) is known as the Etard reaction. This matches with List-II (II).
4. Reaction (D): Formation of benzaldehyde (C₆H₅CHO) from benzene in the presence of CO, HCl, and anhydrous AlCl₃ is an example of the Gattermann Koch reaction. This matches with List-II (I).

Thus, the correct match is:

• A (IV): Rosenmund reaction
• B (III): Stephen reaction
• C (II): Etard reaction
• D (I): Gattermann Koch reaction

Therefore, the correct answer is: A(IV), B(III), C(II), D(I)
