An important example of this phenomenon is the keto-enol type, with the keto form the more stable due to the greater strength of a carbony double bond.

These molecules have the same formula but not the same structure, and cannot be independently isolated. All four DNA bases exist in these forms, and enol ones of guanine can lead to mutations and GT pairings. They also explain why pure enols generally don't exist. FTP, name these rapidly interconverting isomers that differ only in the placement of p-electrons and hydrogen.
