Compounds that transfer electron pairs to electrophiles in order to form chemical bonds with them are referred to as "nucleophiles."

Any ion or molecule with a free electron pair or a pi bond carrying two electrons has the ability to act as a nucleophile.

Definition of electrophile-

In chemistry, an electrophile is an atom or molecule that seeks out another atom or molecule that has an electron pair accessible for bonding in a chemical

Reaction.

Lewis’s acids (compounds that receive electron pairs) are electrophilic chemicals, and many of them are Bronsted acids.

• The intermediate is more likely to collide with the nucleophile that is present in higher concentration.
• Because the solvent concentration is substantially higher than the other nucleophile's concentration. (For example, in part a, the concentration of CH₃OH is much greater than the concentration of Cl^-), the major product will come from the reaction of the solvent with the intermediate.
• Because there are two equivalents of NaI and one equivalent of HBr, the nucleophile in component b is most likely I^-.
