How does one read skeletal formula
Skeletal formula is a way of representing the structure of a molecule by using lines and dots. The lines represent the bonds between the atoms, and the dots represent the atoms themselves. Skeletal formula can be used to represent both organic and inorganic molecules.
To read a skeletal formula, you need to know the following rules:
- Each line represents a single bond.
- Each dot represents an atom.
- Carbon atoms are not usually shown, but they are assumed to be present at the intersections of the lines.
- Hydrogen atoms are not usually shown, but they can be added to the formula if necessary.
- Other atoms are shown by their chemical symbols.
For example, the skeletal formula for methane is CH4. This formula shows that methane has one carbon atom and four hydrogen atoms. The carbon atom is not shown, but it is assumed to be present at the intersection of the four lines. The hydrogen atoms are shown by the four dots.
Skeletal formula can be a useful way to represent the structure of a molecule, but it is important to remember that it is only a two-dimensional representation of a three-dimensional molecule.
