What is the difference between molecular dipoles, and an ionic interaction?

Answer 1

Well, a dipole refers to charge separation....

In contrast, the charges in an ionic compound are SO FAR apart that we obtain individual ions.

#stackrel(delta^+)H-stackrel(delta""^(-))Cl#...is a molecule...and across the covalent bond, the chlorine atom polarizes electron density towards itself...and the result is a molecular dipole...

On the other hand in #Na^+Cl^(-)# there are discrete #Na^+# and #Cl^-# ions....and no suggesting of a covalency, i.e, sharing of electron density...

Molecular dipoles result from an unequal distribution of electron density within a molecule, creating a partial positive and partial negative charge. Ionic interactions occur between ions of opposite charges, such as between a positively charged cation and a negatively charged anion. While molecular dipoles involve polar molecules, ionic interactions involve the attraction between charged species.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
