Draw the products of each Lewis acid-base reaction. Label the electrophile and nucleophile.

a.

b.

c.

The product created after the Lewis acid-base reaction is referred to as the Lewis acid-base adduct. A coordinate covalent bond is present in the final product of the Lewis acid-base reaction.

Lewis acids are also referred to as electrophiles, whereas nucleophiles are referred to as Lewis bases.

a. The compound ${\text{CH}}_3{\text{SCH}}_3$ is regarded as the electrophile, and the compound ${\text{AlCl}}_3$ is the nucleophile. The Lewis acid-base reaction can be given as follows:

Identification of electrophile and nucleophile in reaction a

b. The compound ${\text{BF}}_3$ is considered as the electrophile, and the compound ${\text{CH}}_3{\text{COCH}}_3$ is the nucleophile. The Lewis acid-base reaction can be given as follows:

Identification of electrophile and nucleophile in reaction b

c. The cyclohexane comprising a positive charge is the electrophile and ${\text{H}}_2\text{O}$ is the nucleophile. The reaction of the Lewis acid with a Lewis base is

given below.
