Question
Chapter 5, Problem 5SC
Interpretation Introduction
Interpretation:
Whether the bond between two atoms of the same element can be polar, or not, is to be determined.
Concept Introduction:
Dipole forces exist between polar molecules, which depend upon the polarity of the molecules.
Polar molecules attract each other, whereas, non-polar molecules do not.
Polar molecules do not mix with non-polar molecules.
Molecules having one highly electronegative atom form permanent dipoles which creates strong attractive forceswith similar molecules.
In some polyatomic molecules, the polar bonds cancel each other.
