Chapter 11, Problem 32PE

(a)

Interpretation Introduction

Interpretation:

The bonding nature of $\text{HCl}$ has to be classified.

Concept Introduction:

An electronegativity of an atom gives information about the strength that the atom has for attracting a pair of shared electrons.  The greater the attraction for a pair of shared electrons when the electronegativity value is high.  Consequently, when two different electronegative atoms share a pair of electrons, one atom becomes partially positive and the other atom becomes partially negative due to the attractive forces for the pair of electrons.

(b)

Interpretation Introduction

Interpretation:

The bonding nature of ${\text{BaCl}}_{\text{2}}$ has to be classified.
