Alkenols

Classification of Alkenols
Allyl alcohol: hydroxyl group on the sp 3 hybridized carbon atom
Enol of acetone : hydroxyl group on the sp 2 -hybridized carbon atom. (In equilibrium, 99.9998% of acetone is in the keto and 0.0002% in the enol form.)

Alkenols ( hydroxyalkenes ) are organic-chemical compounds which, in addition to the carbon-carbon double bond, also have a hydroxyl group . Alkenols are (intermediate) products of the chemical industry and the metabolism of animals and plants. Alkenols occur more frequently among the terpenoids , where they are the cause and formative for the smell and taste of many plants and where they are used as a spice .

A special group are the enols , which are in keto-enol tautomerism to aldehydes or ketones . The hydroxyl group is on an sp ² -hybridized carbon atom of the alkenyl radical.

This group includes:

• Allyl alcohol - basic chemical substance, the simplest stable representative of this group
• Vinyl alcohol - the simplest representative, unstable
• Hexenols - important fragrances,
• Citronellol ,
• Isoprenol ,
• Rhodinol ,
• 10-undecen-1-ol
