Stick Notation for Organic Molecular Structures The molecular structure of (E)-B-damascone is represented below. In such shorthand diagrams, the end of each line segment, if not labelled with a chemical symbol, corresponds to a carbon atom. Hydrogen atoms bonded to carbon are frequently not drawn but are always inferred to complete the valence shell for each C atom. Non-bonding electrons for N and O atoms are also omitted from the diagram but can be inferred to complete those valence shells....
