Match the LIST-I with LIST-II

To solve this question, we need to match the reactions from LIST-I to the correct products in LIST-II based on known chemical processes:
Thus, the correct matching is:
| LIST-I | LIST-II |
|---|---|
| A. Swarts reaction | IV. Ethyl fluoride |
| B. Sandmeyer's reaction | III. Cyanobenzene |
| C. Wurtz Fittig reaction | I. Ethyl benzene |
| D. Finkelstein reaction | II. Ethyl iodide |
The correct answer is: A-IV, B-III, C-I, D-II.
The matching of reactions with their corresponding products is as follows:
A. Swarts reaction:
Produces Ethyl fluoride (IV) through the reaction:
R-Cl/Br + Metal fluoride → R-F
B. Sandmeyer's reaction:
Produces Cyanobenzene (III) through the reaction:
Ar-N2+Cl- + CuCN → Ar-CN
C. Wurtz-Fittig reaction:
Produces Ethyl benzene (I) through the reaction:
Ar-X + R-X + 2Na → Ar-R + 2NaX
D. Finkelstein reaction:
Produces Ethyl iodide (II) through the reaction:
R-Cl/Br + NaI → R-I + NaCl/NaBr
The correct matches are:
A-IV, B-III, C-I, D-II
