Question

Match List - I with List - II.

List - I		List - II
(a)		(i)	Hell-VolhardZelinsky reaction
(b)		(ii)	Gattermann-Koch reaction
(c)		(iii)	Haloform reaction
(d)		(iv)	Esterification

Choose the correct answer from the options given below.

• A. (a)-(ii), (b)-(iii), (c)-(iv), (d)-(i)
• B. (a)-(iv), (b)-(i), (c)-(ii), (d)-(iii)
• C. (a)-(iii), (b)-(ii), (c)-(i), (d)-(iv)
• D. (a)-(i), (b)-(iv), (c)-(iii), (d)-(ii)

Answer 1

The Correct Option is A

To solve the question, we need to match the given reactions in List - I with their corresponding names in List - II.

1. Image (a):

   

   • The reaction involves CO and HCl in the presence of Anhyd. AlCl₃ and CuCl. This is the Gattermann-Koch reaction, which is used for formylation of aromatic compounds.
2. Image (b):

   

   • The reaction structure is a classic haloform reaction, where a ketone reacts with halogens in basic conditions, producing a haloform.
3. Image (c):

   

   • The reaction involves an alcohol and a carboxylic acid with conc. H₂SO₄, leading to ester formation, which is known as esterification.
4. Image (d):

   

   • The reaction uses X₂/Red P followed by H₂O, characteristic of the Hell-Volhard-Zelinsky reaction, which brominates carboxylic acids at the α-position.

Based on the above analysis, the correct matches are:

• (a) - (ii) Gattermann-Koch reaction
• (b) - (iii) Haloform reaction
• (c) - (iv) Esterification
• (d) - (i) Hell-Volhard-Zelinsky reaction

Therefore, the correct answer is: (a)-(ii), (b)-(iii), (c)-(iv), (d)-(i).
