JEE Main levelSingle correct optionDifficulty 2 of 3o3074

Match the named reaction in List I with the transformation in List II. Which combination is correct? List I: P Finkelstein; Q Swarts; R Williamson; S Gabriel. List II: 1 ; 2 ; 3 ; 4 potassium phthalimide, then hydrazine, giving .

  1. AP-2, Q-1, R-3, S-4
  2. BP-2, Q-1, R-4, S-3
  3. CP-3, Q-2, R-1, S-4
  4. DP-1, Q-2, R-3, S-4

Answer: A

Finkelstein: chloride or bromide replaced by iodide with NaI in acetone (2). Swarts: halide replaced by fluoride with a metal fluoride such as AgF (1). Williamson: alkoxide plus alkyl halide gives an ether (3). Gabriel: potassium phthalimide alkylation then hydrazinolysis gives a primary amine (4).
