WebUn composé organophosphoré est un type de composé organique comportant au moins un atome de phosphore. In organic chemistry, phosphonates or phosphonic acids are organophosphorus compounds containing C−PO(OR)2 groups (where R = alkyl, aryl, or just hydrogen). Phosphonic acids, typically handled as salts, are generally nonvolatile solids that are poorly soluble in organic solvents, but soluble in water and … See more Phosphonates feature tetrahedral phosphorus centers.
