Coordination Compounds

Acetanilide, with the molecular formula C8H9NO, has a molecular weight of 135.16 g/mol.  Acetanilide is also known as N-phenylacetamide, N-phenylethanamide, and methanol. It is a fact that the compound acetanilide was accidentally prepared. Carl Duisberg, a scientist performing the synthesis of phenacetin from nitrophenol, somehow discovered acetanilide in 1886.  Acetanilide is prepared when we heat acetic […]

Every chemical compound wants to attain maximum stability, which holds for coordination compounds. It refers to the extent of association between the metal ion and the ligands when they are at equilibrium. The stability can be expressed by the formation constant, which is the ratio of the concentration of product and reactants raised to the

The spectrochemical series is a classification system for ligands based on how well they interact with metal ions. The nature of the ligands is a critical component in determining whether a transition metal complex is high-spin or low-spin. The strength of the ligand’s interaction with the metal affects the d orbital energy splitting. Ligands that

Magnesium dihydroxide or magnesium hydroxide, popularly known as milk of magnesia, is a chemical compound with the formula Mg(OH)2. This chemical compound can be found in the form of the mineral brucite in nature. Milk of magnesia is a white substance that has a very low water solubility under ordinary temperature and pressure conditions. It’s

The Hofmann Elimination reaction was developed in 1851 by the famous German Chemist August Wilhelm von Hofmann. The Hofmann Elimination is also known as exhaustive Methylation. The Hofmann Elimination Reaction is based on the Hofmann Rule. Hofmann Rule emphasizes that the major product in reactions such as the Hofmann Elimination as well other Elimination reactions

A group or system comprising different atoms or ions linked to each other in a close or complicated way is known as a complex. A coordinate complex consists of a central atom, usually metallic and known as the coordination centre. The atoms surrounding the central atoms are known as ligands or complexing agents. A complex

The atomic number of an element is defined as the total number of electrons or protons in an atom. Effective atomic number is defined as the total number of electrons around the metal (its own electrons + the electrons donated by the ligands). It is abbreviated as EAN or Zeff, and effective atomic number rule

Diazonium salts are compounds with the general formula R−N2+ X-. R can either be an alkyl or an aryl group. X- holds Cl-, Br-, HSO4-, BF4- etc.  The term combines three words: ‘di’ means ‘two’, ‘azo’ means nitrogen,’ and ‘ium’ means cationic. They are named by suffixing diazonium to the name of the parent alkyl
