Definitions:

Hydrogen Bonding

A weak chemical bond between an electronegative atom, like oxygen or nitrogen, and a hydrogen atom bound to another electronegative atom.

Dispersion Forces

Weak intermolecular forces of attraction, also known as London dispersion forces, arising from temporary shifts in electron density in nonpolar molecules.

General Formula

A representation of the composition of any member of a family of compounds, illustrating a common structural feature among them.

Cyclic Alkanes

Alkanes that contain a ring of carbon atoms in their molecular structure, differing from straight-chain alkanes.
