A univalent radical or functional group (–OH) in organic chemistry; present in alcohols, phenols, carboxylic acids and certain other classes of compounds
The OH anion which has a single negative charge, and provides the characteristics common to bases (See base )
The atmosphere's primary oxidizing agent, this is an ionic (electrically charged) molecule composed of one oxygen and one hydrogen atom (OH) Present as a gas in the atmosphere, hydroxyl reacts easily with methane; this reaction leads to the production of CO and CO2 Because it reacts in this way with several different compounds, including CFCs, hydroxyl (which is only present as a gas, in minute quantities in the atmosphere) is dubbed "the detergent of the atmosphere " Since individual OH molecules exist only temporarily, during the intermediate stages of chemical reactions, they cannot be measured directly Thus, the concentration and variability of concentration of these ions are virtually unknown OH is the main sink for methane, and for all of the hydrogenated halocarbons (including the CFCs); and it is an important aspect of the chemistry of tropospheric ozone It is therefore crucial for determining future changes in these substances (Source: Mintzer, 1992)
A univalent radical or functional group, (-OH), in organic chemistry; present in alcohols, phenols, carboxylic acids and certain other classes of compounds
A compound radical, or unsaturated group, HO, consisting of one atom of hydrogen and one of oxygen
It is a characteristic part of the hydrates, the alcohols, the oxygen acids, etc
