NEET2009ChemistryChemical Bonding and Molecular StructureActual
In solvents like DMSO, acetonitrile, F ⁻ ion of dissolved NaF is more reactive than in methyl alcohol becasue
Options
- ACH ₃ OH is more polar than DMSO and CH ₃ CN
- BCH ₃ OH is less polar than DMSO and CH ₃ CN
- Cunsolvated F ⁻ ion is DMSO or CH ₃ CN acts more efficiently as nucleophile
- D- OH group is a better leaving group than F ⁻ ion.
Correct answer
C. unsolvated F ⁻ ion is DMSO or CH ₃ CN acts more efficiently as nucleophile
Step-by-step solution
In methyl alcohol, F ⁻ ion is solvated but in DMSO or CH ₃ CN (aprotic solvent) F ⁻ ion is not solvated. Unsolvated F ⁻ ion acts more efficiently as a nucleophile.
