Chapter 9, Problem 9.132QP

Interpretation Introduction

Interpretation:

The polar bond and the covalent single bond length have to be given.  The molecular formula of a binary compound and its electron-dot formula has to be drawn.

Concept introduction:

Polar bond: polar bond in which the bonding electrons are not shared equally and spend more time near one atom than the other

Non-polar: bond or molecule in which the centers of positive and negative charge coincide

Lewis structure otherwise known as Lewis dot diagrams or electron dot structures that show the bond between atoms and lone pairs of electrons that are present in the molecule.  Lewis structure represents each atom and their position in structure using the chemical symbol.  Excess electrons forms the lone pair are given by pair of dots, and are located next to the atom.
