Chapter 15, Problem 15.30A

Interpretation Introduction

Interpretation:

Draw the Lewis structures for each species in the reaction shown above and show the curved arrow that designates the electron pair that is donated from the Lewis base to the Lewis acid.

Concept introduction:

• A Lewis acid is an electron pair acceptor, rather than a Bronsted acid that donates H+ ions.
• A Lewis base is an electron pair donor and donates electrons to the Lewis acid. This differs from the Bronsted base which is a proton acceptor only.

To classify:The Lewis structure of the above reaction mechanism.

Given:

${\text{BeCl}}_{\text{2}}\text{+}{\text{2Cl}}^{\text{-}}\to {\text{BeCl}}_{\text{4}}^{\text{2-}}$
