2 C(OH)CH 2 C 6 H 5, and is related to triphenylethylene, from which it can be prepared by hydration. It is the structural analog of two drugs, the never-marketed antiestrogen ethamoxytriphetol (MER-25) [1]: 7 and the withdrawn lipid-lowering agent triparanol, [2] as both contain the 1,1,2-triphenylethanol moiety within their structure.
Skeletal structural formula of Vitamin B 12.Many organic molecules are too complicated to be specified by a molecular formula.. The structural formula of a chemical compound is a graphic representation of the molecular structure (determined by structural chemistry methods), showing how the atoms are possibly arranged in the real three-dimensional space.
When necessary, the position of the hydroxyl group is indicated by a number between the alkane name and the -ol: propan-1-ol for CH 3 CH 2 CH 2 OH, propan-2-ol for CH 3 CH(OH)CH 3. If a higher priority group is present (such as an aldehyde , ketone , or carboxylic acid ), then the prefix hydroxy- is used, [ 19 ] e.g., as in 1-hydroxy-2 ...
The Genesis creation narrative is the creation myth [a] of both Judaism and Christianity, [1] told in the Book of Genesis ch. 1–2. While the Jewish and Christian tradition is that the account is one comprehensive story, [2] [3] modern scholars of biblical criticism identify the account as a composite work [4] made up of two stories drawn from different sources.
A compound's empirical formula is a very simple type of chemical formula. [27] It is the simplest integer ratio of the chemical elements that constitute it. [28] For example, water is always composed of a 2:1 ratio of hydrogen to oxygen atoms, and ethanol (ethyl alcohol) is always composed of carbon, hydrogen, and oxygen in a 2:6:1 ratio.
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.

The surfaces of mineral particles inside deep-ocean hydrothermal vents have catalytic properties similar to those of enzymes and can create simple organic molecules, such as methanol (CH 3 OH) and formic, acetic, and pyruvic acids out of the dissolved CO 2 in the water, if driven by an applied voltage or by reaction with H 2 or H 2 S.
