Explanation:

Examples of nucleophiles are anions such as Cl−, or a compound with a lone pair of electrons such as NH3 (ammonia), PR3. In the example below, the oxygen of the hydroxide ion donates an electron pair to form a new chemical bond with the carbon at the end of the bromopropane molecule...

Examples of anionic nucleophiles includes Cl^{-} , NH2 , OH^{-},R-MgX

Explanation:

  • Anionic nucleophiles are Cl^{-} , NH2 , OH^{-},R-MgX .
  • They can be reversible depending on the basicity.
  • In this the mechanism can involve sequential 1,2 addition or 1,2 elimination steps.
  • Here the conjugate base is always a stronger nucleophile.
  • Acid catalysis generally retards the reaction.
  • With anionic nucleophiles reactions are irreversible.
  • Reaction with anionic nucleophiles are in equilibrium, if nucleophiles and the leaving groups are having the same base strength.
