![]() Kekule: Lewis structures using lines to represent covalent bonds and showing all atoms and lone pair electronsīond-line (Skeletl-line): shows bonds between carbon atoms and heteroatoms) (with lone pair electrons when requested)Ĭondensed: all atoms are written to communicate structure without drawing any chemical bonds based on the carbon backbone There are three primary methods to communicate chemical structure of organic molecules: Some of these shorthand ways of drawing molecules give us insight into the bond angles and relative positions of atoms in the molecule, while some notations eliminate the carbon and hydrogen atoms and only indicate the heteroatoms (the atoms that are NOT carbon or hydrogen). Knowing these patterns, we can fill in the missing structural information. Shorthand notations to represent organic molecules rely on our knowledge of common neutral bonding patterns. Note: The review of general chemistry in sections 1.3 - 1.6 is integrated into the above Learning Objective for organic chemistry in sections 1.7 and 1.8.
