Why this chapter?
Organic chemistry is not always about bond-forming reactions. Some interactions are electrostatic, while others involve weak forces of attraction that hold molecules together, affecting how snuggly they pack. Their attractive strength is significant enough to affect various physical, chemical, and biological properties.
For example, solids pack more strongly than liquids or gases due to their stronger intermolecular attractive force. Salt dissolves in water due to the interaction between salt ions and water molecules. Water freezes as ice crystals with a lot of vacant spaces in between; the folding of our DNA and even how the blood flows in our bodies without sticking or holding onto our organs and tissues has a lot to do with the intermolecular attractive forces.
This chapter extensively covers the most potent intermolecular forces in organic chemistry - Ion-dipole, Ion-induced dipole, Vander Waals forces (Debye, Keesom, and London), and Hydrogen bonding interactions. We study the scenarios in which they occur, their strength, and their impact with plenty of examples.
