We'll start with molecular formulas, which simply list the types and numbers of atoms in a molecule, offering no structural insights. Then we’ll look at structural formulas, which build on molecular formulas by showing the connections between atoms, thus giving a basic view of the molecule's structure. Lastly, we'll cover skeletal formulas, which are streamlined representations used mainly in organic chemistry to depict the carbon backbone of molecules, omitting most hydrogen atoms.

Be sure to do the practice problems to really learn to identify and draw each type of formula. Also look carefully at the visual demonstrations that show how each formula type correlates to the actual structure of molecules, aimed at improving understanding and visualization skills.
