Example 2 · difficulty 2/5
In the Finkelstein reaction, R–X + NaI → R–I + NaX, the conversion of a chloroalkane or bromoalkane to the corresponding iodoalkane is carried out specifically in dry acetone because:
- A. water dissolves all the salts equally well, keeping the system at equilibrium
- B. ethanol stabilises the iodoalkane product against further reaction
- C. NaI is soluble in acetone while NaCl/NaBr are insoluble and precipitate out, pulling the equilibrium forward
- D. liquid ammonia complexes with Na⁺ and thereby removes the leaving group
Example 3 · difficulty 1/5
Which of the following alkyl bromides undergoes an SN2 reaction with I⁻ in acetone at the fastest rate?
- A. 1-Bromopropane
- B. Bromomethane
- C. 2-Bromopropane
- D. 1-Bromo-2,2-dimethylpropane
The evidence-first practice loop
- 1. Verify provenanceOfficial paper and final key before accepting a PYQ label.
- 2. Attempt closed-bookExpose the concept or execution gap before rereading.
- 3. Repair and returnClassify the miss and re-practice after a delay.
