Match List - I with List - II.

Choose the correfct answer from the options given below.

To find the correct match, let us analyze each reaction given in List - I step-by-step and identify the corresponding name from List - II:

(a) Benzene reaction with CO, HCl in the presence of Anhydrous AlCl₃ / CuCl:
When benzene or its derivatives are treated with carbon monoxide (CO) and hydrogen chloride (HCl) in the presence of anhydrous aluminum chloride (AlCl₃) and cuprous chloride (CuCl), benzaldehyde or substituted benzaldehyde is formed. This reaction is known as the Gattermann-Koch reaction.
Therefore, (a) matches with (ii).

(b) Methyl ketone (R-CO-CH₃) reaction with Sodium Hypohalite (NaOX):
Ketones containing at least one methyl group linked to the carbonyl carbon atom (methyl ketones) are oxidized by sodium hypohalite (NaOX) to sodium salts of corresponding carboxylic acids having one carbon atom less than that of the ketone. The methyl group is converted to haloform (CHX₃). This reaction is known as the Haloform reaction.
Therefore, (b) matches with (iii).

(c) Alcohol (R-CH₂-OH) reaction with Carboxylic Acid (R'-COOH) in the presence of Concentrated H₂SO₄:
Carboxylic acids react with alcohols in the presence of an acid catalyst such as concentrated sulfuric acid (H₂SO₄) to form esters and water. This condensation reaction is known as Esterification.
Therefore, (c) matches with (iv).

(d) Carboxylic acid (R-CH₂COOH) reaction with X₂ / Red Phosphorus followed by water:
Carboxylic acids having an $\alpha$-hydrogen are halogenated at the $\alpha$-position on treatment with chlorine or bromine in the presence of a small amount of red phosphorus, followed by hydrolysis. This reaction is known as the Hell-Volhard-Zelinsky (HVZ) reaction.
Therefore, (d) matches with (i).

Combining all the correct matches:
(a) - (ii)
(b) - (iii)
(c) - (iv)
(d) - (i)

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