For each of the Lewis acid–base reactions in Problem 16.138, draw electron-dot structures for the reactants and products, and use the curved arrow notation to represent the donation of a lone pair of electrons from the Lewis base to the Lewis acid.

Lewis acids are substances that can accept an electron pair, while Lewis bases are those that can donate an electron pair. This definition expands the concept of acids and bases beyond protons, allowing for a broader range of chemical reactions. Understanding these roles is crucial for analyzing reactions where electron pair transfer occurs.

Electron-dot structures, or Lewis structures, visually represent the valence electrons of atoms within a molecule. They help illustrate how atoms bond and the arrangement of electrons, including lone pairs and bonding pairs. Drawing these structures is essential for understanding the interactions between Lewis acids and bases in a reaction.

Curved arrow notation is a method used in organic chemistry to depict the movement of electron pairs during chemical reactions. The tail of the arrow indicates the source of the electrons, while the head points to where the electrons are going. This notation is vital for illustrating the mechanism of Lewis acid-base reactions, showing how electron pairs are transferred.
