CH 3 CH 2 OH . Parentheses are used to indicate multiple identical groups, indicating attachment to the nearest non-hydrogen atom on the left when appearing within a formula, or to the atom on the right when appearing at the start of a formula: (CH 3) 2 CHOH or CH(CH 3) 2 OH . In all cases, all atoms are shown, including hydrogen atoms.

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.
However, the empirical formula for hexane is C 3 H 7. Likewise the empirical formula for hydrogen peroxide, H 2 O 2, is simply HO, expressing the 1:1 ratio of component elements. Formaldehyde and acetic acid have the same empirical formula, CH 2 O. This is also the molecular formula for formaldehyde, but acetic acid has double the number of atoms.

Although acids such as phosphoric acid are written as H 3 PO 4, the protons are attached to oxygen atoms forming hydroxyl groups, so the formula can also be written as OP(OH) 3 to better reflect the structure. Sulfuric acid may be written as O 2 S(OH) 2; this is the molecule observed in the gas phase. The phosphite ion, PO 3− 3, is a strong ...
In order to study gas phase interstellar chemistry, it is convenient to distinguish two types of interstellar clouds: diffuse clouds, with T=30-100 K, and n=10–1000 cm −3, and dense clouds with T=10-30K and density n= 10 4-10 3 cm −3. Ion chemical routes in both dense and diffuse clouds have been established for some works (Hartquist 1990).
The formula, Cu 2 CO 3 (OH) 2 shows that it is halfway between copper carbonate and copper hydroxide. Indeed, in the past the formula was written as CuCO 3 ·Cu(OH) 2. The crystal structure is made up of copper, carbonate and hydroxide ions. [37] The mineral atacamite is an example of a basic chloride. It has the formula, Cu 2 Cl(OH) 3.
