Match List - I with List - II.

Choose the correfct answer from the options given below.

To solve this matching problem, let us analyze each reaction shown in List - I of the image and match it with the correct named reaction in List - II:

Reaction (a):
The image shows a benzene ring reacting with carbon monoxide (CO) and hydrogen chloride (HCl) in the presence of anhydrous aluminium chloride (Anhyd. AlCl₃) and cuprous chloride (CuCl).
This electrophilic aromatic substitution reaction is known as the Gattermann-Koch reaction, which is used for the formulation of benzene to form benzaldehyde.
Therefore, (a) matches with (ii).

Reaction (b):
The image shows a methyl ketone (R-CO-CH₃) reacting with sodium hypohalite (NaOX).
This reaction involves the halogenation of the methyl group followed by cleavage to yield a carboxylate salt and a haloform (CHX₃). This is known as the Haloform reaction.
Therefore, (b) matches with (iii).

Reaction (c):
The image shows a primary alcohol (R-CH₂-OH) reacting with a carboxylic acid (R'COOH) in the presence of concentrated sulfuric acid (Conc. H₂SO₄) as a catalyst.
This condensation reaction between an alcohol and a carboxylic acid to form an ester and water is known as Esterification.
Therefore, (c) matches with (iv).

Reaction (d):
The image shows a carboxylic acid with α-hydrogens (R-CH₂COOH) undergoing treatment with a halogen (X₂) in the presence of red phosphorus (Red P), followed by hydrolysis (H₂O).
This reaction leads to the selective halogenation of the α-carbon of the carboxylic acid and is known as the Hell-Volhard-Zelinsky reaction.
Therefore, (d) matches with (i).

Combining all the individual matches, we get:
(a) - (ii)
(b) - (iii)
(c) - (iv)
(d) - (i)

Thus, the correct option is (a)-(ii), (b)-(iii), (c)-(iv), (d)-(i).
