What is the product of the addition of I-Cl to 1-butene? (Hint: Chlorine is more electronegative than iodine [Table 1.3].)

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.

Iodine will be the electrophile because chlorine is more electronegative than iodine. As a result, it will become connected to the sp² carbon with the most hydrogens.
