Lewis Structures of some Biologically-Interesting Molecules See lecture 10 (starting on page 3 of the notes), lecture 11, and lecture 12 for a description of covalent bonding and Lewis structures. Lewis structures can be found in almost any chemistry laboratory notebook at MIT. They are easy to draw and quickly communicate information about the functional groups and reactivity of small molecules. Below are two examples of molecules frequently used to teach Lewis structure rules with some additional information about the chemical and biological significance of the molecules. Example 1) from page 2 of Lecture 11 notes: Cynanide ion (CN -1 ) Salts of CN -1 , such as sodium cyanide (NaCN) and potassium cyanide (KCN), are used as reagents in organic synthesis. These reagents are very reactive and allow chemists to add
