Question: 80. Match List-I with List-II.
| List-I | List-II |
|---|---|
| A. Haber process | I. Fe catalyst |
| B. Wacker oxidation | II. \mathrm{PdCl_2} |
| C. Wilkinson catalyst | III. \left[\left(\mathrm{PPh_3}\right)_3 \mathrm{RhCl}\right] |
| D. Ziegler catalyst | IV. \mathrm{TiCl_4} with \mathrm{Al}\left(\mathrm{CH_3}\right)_3 |
Choose the correct answer from the options given below:
(1) A-I, B-II, C-IV, D-III
(2) A-II, B-III, C-I, D-IV
(3) A-I, B-II, C-III, D-IV
(4) A-I, B-IV, C-III, D-II
Answer: Option (3)
Explanation:
The Haber process is used for the manufacture of ammonia and employs finely divided iron as the catalyst.
Therefore, A matches with I.
Wacker oxidation is used to convert alkenes into ketones or aldehydes using a palladium(II) chloride catalyst. Hence, B matches with II.
Wilkinson catalyst is a homogeneous catalyst used in hydrogenation reactions and has the formula
\left[\left(\mathrm{PPh_3}\right)_3 \mathrm{RhCl}\right].
Thus, C matches with III.
Ziegler catalyst is used in polymerisation of alkenes and consists of \mathrm{TiCl_4} with organoaluminium compounds such as \mathrm{Al}\left(\mathrm{CH_3}\right)_3. Therefore, D matches with IV.
Hence, the correct matching is A-I, B-II, C-III, D-IV,
which corresponds to option (3).
