The relationship between ketones and their corresponding enols is one of ________.
A) allotropes
B) tautomers
C) enantiomers
D) diastereomers
E) cis-trans isomers
Tautomers
Isomers of organic compounds that differ in the position of protons and electrons but have the same molecular formula, often interconverting in a chemical equilibrium.
Enols
Organic compounds containing a hydroxyl group directly bonded to a carbon atom that is double-bonded to another carbon atom.
Ketones
Ketones are organic compounds characterized by a carbonyl group (C=O) linked to two carbon atoms. They are part of many biological and synthetic substances.

Final Answer :
B
Explanation :
Ketones and their corresponding enols are tautomers, which are isomers that differ in the placement of a hydrogen and a double bond. In this case, the keto form typically predominates over the enol form under normal conditions, but the two forms can interconvert via tautomerization reactions. Allotropes are different forms of the same element, enantiomers are mirror-image stereoisomers, diastereomers are stereoisomers that are not mirror images, and cis-trans isomers are a type of stereoisomerism that arises from restricted rotation about double bonds.
