Assertion : CH3 – CH2 – Cl + NaI\(\text { Acetone }\)
CH3 – CH2 – I + NaCl ↓
Reason : Acetone is polar Aprotic solvent and solubility order of sodium halides decreases dramatically in order NaI > NaBr > NaCl. The last being virtually insoluble in this solvent and a 1° and 2° chloro alkane in acetone is completely driven to the side of Iodoalkane by the precipitation reaction.
