Hydroxy group - Wikipedia
WEBIn chemistry, a hydroxy or hydroxyl group is a functional group with the chemical formula −OH and composed of one oxygen atom covalently bonded to one hydrogen atom. In organic chemistry, alcohols and carboxylic acids contain one or more hydroxy groups.
Hydroxyl group | Definition, Structure, & Facts | Britannica
WEBHydroxyl group (―OH), in chemistry, a functional group with one hydrogen and one oxygen atom. An oxygen atom normally forms two σ bonds with other atoms; the water molecule, H2O, is the simplest and most common example. If one hydrogen atom is removed from a water molecule, a hydroxyl functional.
Hydroxyl Group Definition - Chemistry Term - ThoughtCo
WEBNov 5, 2018 · The term hydroxyl means the radical OH. The functional group -OH is more properly called a hydroxy group. Further, the [OH -] anion, which is called hydroxide, consists of a hydroxy group. Get the definition of hydroxyl group in chemistry and learn how it's different from the hydroxy group.
1.6: Functional Groups - Chemistry LibreTexts
WEBIn the alcohol functional group, a carbon is single-bonded to an OH group (the OH group, by itself, is referred to as a hydroxyl). Except for methanol, all alcohols can be classified as primary, secondary, or tertiary. In a primary alcohol, the carbon bonded to the OH group is also bonded to only one other carbon.
Functional groups (video) | Elements of life | Khan Academy
WEBVarious functional groups can be attached to hydrocarbons, effecting chemical properties. Hydroxyl groups are polar, turn molecules into alcohols, and allow molecules to dissolve in water. Carboxyl groups can donate hydrogen ions, so they make molecules acidic.

WEBJan 22, 2024 · The hydroxy-group is one of many functional groups studied in organic chemistry. The presence of a hydroxy group indicates that the molecule is either an alcohol or a carboxylic acid. The chemical representation of a hydroxy group is – OH, indicating an oxygen atom covalently bonded to a hydrogen atom.
Hydroxyl Group - Definition and Quiz | Biology Dictionary
WEBLast Updated: April 28, 2017. Hydroxyl Group Definition. A hydroxyl group is a functional group that attaches to some molecules containing an oxygen and hydrogen atom, bonded together. Also spelled hydroxy, this functional group provides important functions to both alcohols and carboxylic acids.
1.9: Functional Groups - Biology LibreTexts
WEBA hydroxyl (alcohol group) is an –OH group covalently bonded to a carbon atom. The oxygen atom is much more electronegative than either the hydrogen or the carbon, which will cause the electrons in the covalent bonds to spend more time around the oxygen than around the C or H.
8.1: Naming the Alcohols - Chemistry LibreTexts
WEBFind the longest chain containing the hydroxy group (OH). If there is a chain with more carbons than the one containing the OH group it will be named as a subsitutent. Place the OH on the lowest possible number for the chain.
Properties of Alcohols - Chemistry LibreTexts
WEBJan 23, 2023 · Alcohols contain the hydroxy functional group (-OH), bonded to a carbon atom of an alkyl or substituted alkyl group. The functional group of an alcohol is the hydroxyl group, –OH. Unlike the alkyl halides, this group has two reactive covalent bonds, the C–O bond and the O–H bond.
