Sulfuric acid contains two hydroxy groups.. Water, alcohols, carboxylic acids, and many other hydroxy-containing compounds can be readily deprotonated due to a large difference between the electronegativity of oxygen (3.5) and that of hydrogen (2.1).
The letter "o" ("oh") is also used in spoken English as the name of the number 0 when saying times in the 24-hour clock, particularly in English used by both British and American military forces. Thus 16:05 is "sixteen oh five", and 08:30 is "oh eight thirty". [25] The use of O as a number can lead to confusion as in the ABO blood group system ...
The formation of O 2 occurs in the gas phase via the neutral exchange reaction between • O and • HO, which is also the main sink for • HO in dense regions. [20] We can see that atomic oxygen takes part both in the production and destruction of • HO, so the abundance of • HO depends mainly on the H + 3 abundance.
The O–H–O distance is very short, at 265 pm; the hydrogen is not equidistant between the oxygen atoms and the short OH bond makes an angle of 12° with the O–O line. [45] A similar type of hydrogen bond has been proposed for other amphoteric hydroxides, including Be(OH) 2 , Zn(OH) 2 , and Fe(OH) 3 .
For example, sugar dissolves in water because both share the hydroxyl functional group (−OH) and hydroxyls interact strongly with each other. Plus, when functional groups are more electronegative than atoms they attach to, the functional groups will become polar, and the otherwise nonpolar molecules containing these functional groups become ...
General structure of a sulfonic acid with the functional group indicated in blue. In organic chemistry, sulfonic acid (or sulphonic acid) refers to a member of the class of organosulfur compounds with the general formula R−S(=O) 2 −OH, where R is an organic alkyl or aryl group and the S(=O) 2 (OH) group a sulfonyl hydroxide.

The self-ionization of water (also autoionization of water, autoprotolysis of water, autodissociation of water, or simply dissociation of water) is an ionization reaction in pure water or in an aqueous solution, in which a water molecule, H 2 O, deprotonates (loses the nucleus of one of its hydrogen atoms) to become a hydroxide ion, OH −.
OH + 3 ···:OH 2 (18 kJ/mol [20] or 4.3 kcal/mol) The strength of intermolecular hydrogen bonds is most often evaluated by measurements of equilibria between molecules containing donor and/or acceptor units, most often in solution. [ 21 ]
