Match List - I with List - II.

List - I : (a) benzene \(\xrightarrow[\text{Anhyd. }AlCl_3/CuCl]{CO,\ HCl}\) (b) \(R-CO-CH_3 + NaOX \rightarrow\) (c) \(R-CH_2-OH + R'COOH \xrightarrow{\text{Conc. }H_2SO_4}\) (d) \(R-CH_2COOH \xrightarrow[\text{(ii) }H_2O]{\text{(i) }X_2/\text{Red P}}\)

List - II : (i) Hell-Volhard-Zelinsky reaction (ii) Gattermann-Koch reaction (iii) Haloform reaction (iv) Esterification

Choose the correct answer from the options given below.

benzene ring with CO, HCl, Anhyd AlCl3/CuCl arrow (List I item a)

1. (a)-(iv), (b)-(i), (c)-(ii), (d)-(iii)

2. (a)-(iii), (b)-(ii), (c)-(i), (d)-(iv)

3. (a)-(i), (b)-(iv), (c)-(iii), (d)-(ii)

4. (a)-(ii), (b)-(iii), (c)-(iv), (d)-(i)

Answer: 4. (a)-(ii), (b)-(iii), (c)-(iv), (d)-(i)

Key idea: match each reaction with its name.

  • (a) benzene + CO, HCl, anhydrous \(\mathrm{AlCl_3}\)/CuCl: Gattermann-Koch (ii)
  • (b) methyl ketone + NaOX: haloform (iii)
  • (c) alcohol + carboxylic acid, conc. \(\mathrm{H_2SO_4}\): esterification (iv)
  • (d) acid + \(\mathrm{X_2}\)/red P: Hell-Volhard-Zelinsky (i)

So (a)-(ii), (b)-(iii), (c)-(iv), (d)-(i).
