Simpler (abbreviated) diagrams often take-up less space. Important parts of the molecules are more obvious, i.e. have more prominence, in skeletal diagrams than in most fully displayed formulae. This type of diagram is commonly used in the chemical industry, hence useful to be familiar with. When and where are skeletal formulae used ?

Answer. 1.12: Drawing Chemical Structures is shared under a license and was authored, remixed, and/or curated by Steven Farmer, Dietmar Kennepohl, Krista Cunningham, Tim Soderberg, William Reusch, & William Reusch. Kekulé Formulas or structural formulas display the atoms of the molecule in the order they are bonded.
Chemical structures are usually represented by the skeletal formula, which provides a graphical representation of the molecule with most hydrogens omitted for clarity. Full Lewis structures are used only rarely, when a more complete drawing is needed, because they are often harder to read than skeletal structures.
Skeletal formulae. In a skeletal formula, all the hydrogen atoms are removed from carbon chains, leaving just a carbon skeleton with functional groups attached to it. For example, we've just been talking about butan-2-ol. The normal structural formula and the skeletal formula look like this: In a skeletal diagram of this sort
Drawing Bond-Line structures efficiently requires adhering to certain guidelines. These include: Zig-zag lines: Always draw structures in neat zig-zags, as shown in [figure 03]. Avoid drawing them like a picket fence or with exaggerated angles. Triple bonds should be linear: This guidance stems from the geometry of the sp-hybridized atoms.
Skeletal structures is the most common type of the molecular representation in organic chemistry. In the skeletal structures we show the absolute minimum that we need to represent a molecule in a non-ambiguous way. Thus, skeletal drawings have certain rules we use to draw them: Carbons and Hydrogens are implicit.
