Q.
The correct order of reactivity of ${CH}_{3} Br$ in methanol with the following nucleophiles is

$F^{-}, I^{-}, C_{2} H_{5} O^{-} and C_{6} H_{5} O^{-}$ [2026]

Solution

Q.
The correct order of reactivity of ${CH}_{3} Br$ in methanol with the following nucleophiles is

$F^{-}, I^{-}, C_{2} H_{5} O^{-} and C_{6} H_{5} O^{-}$ [2026]

1 $I^{-} > C_{6} H_{5} O^{-} > F^{-} > C_{2} H_{5} O^{-}$

2 $I^{-} > F^{-} > C_{6} H_{5} O^{-} > C_{2} H_{5} O^{-}$

3 $I^{-} > C_{2} H_{5} O^{-} > C_{6} H_{5} O^{-} > F^{-}$

4 $I^{-} > C_{2} H_{5} O^{-} > F^{-} > C_{6} H_{5} O^{-}$

Ans.
(3)

$Order of nucleophilicity:$
