Chapter 5.9, Problem 5.22YT

Interpretation Introduction

Interpretation:

The nature of $\text{C-H}\text{and}\text{C-C}$ bonds in hexane and pentane has to be identified.  Also the reason for non-polar nature of these compounds has to be explained.

Concept Introduction:

Polar molecules possess charge separation in them, which arises due to the difference in the electronegativities between the atoms in a molecule.  So, polar molecules possess a permanent dipole moment in them.  Increase in difference between electronegativity of two bonded atoms increases polar nature of the bond.
