What is the chemical and common name for H OH?

Answer 1

This compound is copper(II) hydroxide.

Answer 2

OH2 is a very nonstandard way to write H2O, which is water. (When I was a high school student, a fad - which, fortunately, was short-lived - was to write it as "HOH" to show one of two things - that it was a hydrogen bonded to a hydroxy group and to show the order the atoms lined up in the compound. Thank Buddha we don't try to show atomic alignment in all compounds...imagine notating bromophenol blue dye - C19H10BR4O5S - that way. This thing has three aromatic rings held together with another carbon atom...a very ugly molecule to write a Lewis diagram for, but the 3D model of it is most satisfying...)

A common way to write chemical compounds is the Hill System, which was created by Edwin A. Hill of the US Patent and Trademark Office in 1900. It's most used for notating organic compounds, because it calls for the carbon atoms to be listed first, then the hydrogens and then all the other elements in the compound, in alphabetical order. Under Hill System, water is notated H2O because H comes before O in the alphabet.

Another popular way is to notate by electronegativity - an atom's tendency to attract electrons to itself. In this system, the least electronegative element is listed first...so, sulfuric acid is H2SO4 and not H2O4S:

H = 2.20 electronegativity

S = 2.58

O = 3.44

The hydroxy group is special: it's notated "backwards" (according to either Hill or electronegativity it should be HO) because of bonding. The hydroxy group has to bond to something like...oh, an ethane molecule to form ethanol or a sodium atom to form sodium hydroxide. The group is going to bond into the molecule through the oxygen atom rather than the hydrogen atom, so they write it "OH" to make that more clear.

Answer 3

The chemical name for H-O-H is water, and the common name is dihydrogen monoxide.

Answer 4

OH- is also commonly referred to as the Hydroxide Ion.

Answer 5

OH is hydroxide, consisting of one atom of hydrogen and one of oxygen.

Answer 6

HOH, more commonly written H2O is the formula for dihydrogen monoxide, also known as water.

Answer 7

There is no such substance as 'OH' . However, there is an anion(ion) ' OH^-' .

Notie it has a negative charge, which MUST be shown.

Answer 8

Hydroxide.

Answer 9

OH

Answer 10

Water.
