Chapter 14, Problem 14A.2BE

Interpretation Introduction

Interpretation:

The resultant of two dipole moments of magnitude $\text{2}\text{.5}\text{D}$ and $\text{0}\text{.50}\text{D}$ which make an angle of $120°$ has to be calculated.

Concept introduction:

Polarized bonds are a result of the electronegativity difference between bonding atoms.  The more electronegative atom acquires a partial negative charge and the less electronegative atom acquires a partial positive charge.  This results in the formation of a dipole in the bond between the two atoms.
