Chapter 1, Problem 41PP

Interpretation Introduction

Interpretation:

To draw Lewis dot structure for ${\text{AlBr}}_{\text{4}}{}^{-}$ and geometry of the aluminium atom has to be found.

Concept introduction:

Lewis dot structures show the bonding between atoms of a molecule and lone pair of electrons that may exist in the molecule.  This structure can be drawn for any covalently bonded molecule and coordination compounds.  A single bond is formed by sharing of two electrons, double bond by sharing of four electrons and triple bond by sharing of 6 electrons.  The atoms contain higher valence electrons are drawn first and then the least valence electron containing atoms are drawn.
