Chapter 15, Problem 65E

Interpretation Introduction

Interpretation:

The error in the molecular picture of a soap molecule in water is to be identified.

Concept Introduction:

Polar molecules attract each other, whereas non-polar molecules are not attracted by them.

Polar molecules do not mix with non-polar molecules.

Polar molecules mix with other polar molecules, while non-polar molecular mix with other non-polar molecules only.

Soap molecules have polar and non-polar sides, which helps in the dissolution of non-polar molecules to the non-polar side and polar molecules to the polar side.
