Question:
Which of the following is strongest nucleophile
Which of the following is strongest nucleophile
Updated On: Dec 19, 2025
- $Br^{-}$
- $: OH^{-}$
- $: CN^{-}$
- $C_2 H_5 \bar{O}$
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
The strength of nucleophile depends upon the nature of alkyl group $R$ on which nucleophile has to attack and also on the nature of solvent. The order of strength of nucleophiles follows the order :
$CN^{-} > I^{-} > C_6H_5O^{-} > OH^{-} > Br^{-} > Cl^{-} $
$CN^{-} > I^{-} > C_6H_5O^{-} > OH^{-} > Br^{-} > Cl^{-} $

Hydrocarbons - Reaction Mechanism
Hydrocarbons are organic compounds that are entirely made up of only two kinds of atoms – carbon and hydrogen. Typically, hydrocarbons are colourless gases that have very weak odours.
Mechanism of electrophilic substitution reactions:
According to experimental evidences, SE (S = substitution; E = electrophilic) reactions are supposed to proceed via the following three steps:
- Generation of the electrophile
- Formation of carbocation intermediate
- Removal of proton from the carbocation interm
