Chapter 8, Problem 8.1YT

Interpretation Introduction

Interpretation:

The names of the elementary step under each arrow occurring in Equation $\text{8-2}$ are to be written.

Concept introduction:

In heterolysis step, the bond between the carbon and the leaving group, $\text{C}-\text{L}$, is broken the bonding electrons go with the leaving group, forming carbocation and the ${\text{L}}^{-}$.

The coordination reaction is the Lewis acid-base reaction. A Lewis acid is an electron-pair acceptor, having an atom that lacks an octet. The species which donates electron pair is a Lewis base. In a coordination step, the single curved arrow drawn indicates the flow of electrons from an electron-rich site to an electron-poor site.
