In organic chemistry, phosphonates or phosphonic acids are organophosphorus compounds containing C−PO(OR) 2 groups, where R is an organic group (alkyl, aryl). If R is hydrogen then the compound is a dialkyl phosphite , which is a different functional group.
In organic chemistry, phosphonites are organophosphorus compounds with the formula P(OR) 2 R. ... Oxidation of phosphonites gives phosphonates: 2 P(OR) 2 R + O 2 → ...
The general formula of a phosphoric acid is H n+2−2x P n O 3n+1−x, where n is the number of phosphorus atoms and x is the number of fundamental cycles in the molecule's structure, between 0 and n + 2 / 2 . Pyrophosphate anion. Trimethyl orthophosphate.
They have the general formula R−O−R′, where R and R′ represent the organyl groups. Ethers can again be classified into two varieties: if the organyl groups are the same on both sides of the oxygen atom, then it is a simple or symmetrical ether, whereas if they are different, the ethers are called mixed or unsymmetrical ethers.

For example, the formula of methyl phosphate is CH 3-H 2 PO 4, dimethyl phosphate – (CH 3) 2 HPO 4 and trimethyl phosphate – (CH 3) 3 PO 4. Alkyl phosphates are widely distributed in nature, and form the basis of most biological processes. For example, high energy metabolites such as ATP and PEP are alkyl phosphates, as are nucleic acids ...
They exhibit tautomerism, however, the equilibrium overwhelmingly favours the right-hand (phosphonate-like) form: [11] [12] (RO) 2 POH ⇌ (RO) 2 P(O)H The P-H bond is the site of high reactivity in these compounds (for example in the Atherton–Todd reaction and Hirao coupling ), whereas in tri-organophosphites the lone pair on phosphorus is ...
You can get this essential vitamin as a liquid, softgel, tablet, or capsule, so it should be easy to find the right formula for your lifestyle. 2. Vitamin C.
In chemistry, the term phosphonium (more obscurely: phosphinium) describes polyatomic cations with the chemical formula PR + 4 (where R is a hydrogen or an alkyl, aryl, organyl or halogen group). These cations have tetrahedral structures. The salts are generally colorless or take the color of the anions. [1]
