Chapter 11, Problem 33PE

(a)

Interpretation Introduction

Interpretation:

The bonding nature between atoms of $\text{P}\text{and}\text{I}$ 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 between atoms of $\text{N}\text{and}\text{S}$ has to be classified.
