Alcohols are alcohols having the general structure r₃coh. (or oxiranes) are cyclic ethers having the oxygen atom as part of a three-membered ring. have a hydroxy group as a substituent on a benzene ring. alcohols are alcohols having the general structure rch₂oh. have two alkyl groups bonded to an oxygen atom. have an oh group on a carbon of a c-c double bond. alcohols are alcohols having the general structure r₂choh. contain a hydroxy group bonded to an sp³ hybridized carbon atom.

Explanation:Tertiary alcohol are alcohols having the general structure R₃COH. Epoxide are cyclic ether with a three-membered ring. The basic structure of an epoxide contains an oxygen atom attached to two adjacent carbon atoms of a hydrocarbon. Phenol is an aromatic organic compound with the molecular formula C₆H₅OH. An alcohol contains a hydroxy group (OH group) bonded to an sp3 hybridized carbon atom. Enols are a type of reactive structure or intermediate in organic chemistry that is represented as an alkene with a hydroxyl group attached to one end of the alkene double bond. Alcohols are classified like halides and hydrogens; primary (1°), secondary (2°), or tertiary (3°) depending on the number of carbons bonded to the carbon with the halogen.
