Question

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

Short answer

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.

Step 2

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.
