Chapter 8.4, Problem 37LC

Interpretation Introduction

Interpretation: The result of polar molecules between oppositely charged metal plates needs to be explained.

Concept Introduction: A bond is said to be polar in nature if there is an electronegativity difference between two atoms. Here, the atom with more electronegativity has a partial negative charge and an atom with less electronegativity has a partial positive charge. Not all molecules with polar bonds are polar molecules, but all polar molecules must have polar bonds.

Explanation of Solution

In a polar molecule, there is an electronegativity difference between two or more atoms. This polarity is shown in such a way that there is a negative charge on a more electronegative atom and a positive charge on a less electronegative atom. If the polar molecule is placed between oppositely charged metal plates, the negative end of the polar molecule is oriented closer to the positive plate and the positive end of the molecule is oriented closer to the negative plate.
