Chapter 4, Problem 4.38SP

(a)

Interpretation Introduction

Interpretation:

By using ${\text{δ}}^{\text{+}}{\text{/δ}}^{\text{-}}$ notation, the direction of polarity of each bonds in the given substances has to be shown.

$\text{C-H and C-Cl}$

Concept introduction:

The direction of polarity can be expressed in vector quantity.  Usually del $\text{(δ)}$ symbol has been used which denotes partial negative charge or partial positive charge.

(b)

Interpretation Introduction
