In solvents like DMSO, acetonitrile, `F^(-)` ion of dissolved NaF is more reactive than in methyl alcohol. Explain

A

a.`CH_(3)OH` is more polar than DMSO and `CH_(3)CN`

B

b.`CH_(3)OH` is less polar than DMSO and `CH_(3)CN`

C

c.unsolvated `F^(-)` ion is DMSO or `CH_(3)CN` acts more efficiently as nucleophile

D

d.`-OH` group is a better leaving group than `F^(-)` ion

Text Solution

Verified by Experts

The correct Answer is:
C
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.
