Hydroxyl 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.

In 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.

2024年4月25日 · Hydroxyl is an chemical group that plays a big role in organic chemistry. It is an -OH functional group with an oxygen atom bonded to a hydrogen atom, and it is usually represented as OH. These are the groups that are responsible for the framework and activity of the variety of organic compounds, and this in turn impacts their properties and ...

2018年11月5日 · The hydroxyl group is a functional group consisting of a hydrogen atom covalently bonded to an oxygen atom. The hydroxyl group is denoted by -OH in chemical structures and has a valence charge of -1.

The meaning of HYDROXYL is the chemical group, ion, or radical OH that consists of one atom of hydrogen and one of oxygen and is neutral or negatively charged.

Hydroxyl, on the other hand, refers to the functional group -OH, which consists of one oxygen atom bonded to one hydrogen atom. Unlike hydroxide, hydroxyl is not an ion but a part of a molecule. It is commonly found in organic compounds …

2017年4月28日 · 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.

2017年9月6日 · Hydroxyl is a group of atoms that is bonded to a molecule. Therefore, it is always found as a part of a molecule. There are no existing free forms of hydroxyl groups since the free form of hydroxyl is an unstable radical and radicals react with another molecule in order to become stabilized.

2023年11月21日 · A hydroxyl group is composed of one hydrogen atom bonded to one oxygen atom. Its chemical formula is written as either -OH or HO-. The '-' represents the carbon to which the hydroxyl group is...

2018年5月14日 · hydroxyl group (hīdrŏk´sĬl), in chemistry, functional group [1] that consists of an oxygen atom joined by a single bond to a hydrogen atom. An alcohol [2] is formed when a hydroxyl group is joined by a single bond to an alkyl group [3] or aryl group [4].
