Co-ordination or complex compound refers to a compound in which a metal atom or ion is coordinated to two or more anions or neutral molecules. In most cases, a coordination compound contains one or more complicated ions. For example, K₄[Fe(CN)₆]⁴⁺ is made up of a complex ion, [Fe(CN)₆]⁴⁺. A ligand is a chemical or ionic […]
Introduction A complex compound is one in which two or more anions or neutral molecules are coordinated by a metal atom or ion. A coordination complex contains one or more complicated ions in the majority of cases. K₄[Fe(CN)₆] , for example, is composed of the complex ion [Fe(CN)₆]⁴⁺. During the creation of a complex, a

Bonding in coordination compounds, Chemistry, Class 12, Coordination Compounds, IIT JEECoordination compounds are chemical complexes in which the central metal ion is covalently bonded to ligands (anionic or neutral) that act as Lewis bases. Ligands donate their electron density to the vacant hybridised orbital of the metal. Several theories have been postulated over time to explain the bonding and properties of coordination compounds. These compounds

Bonding in coordination compounds, Chemistry, Class 12, Coordination Compounds, IIT JEEAmbidentate ligand is a type of ligand that will connect to the central metal atom through atoms of two different elements. Mainly ambidentate ligands have quite one donor atom but during dative bond formation, just one of them attaches itself to the central metal atom. A compound during which the central metal atom or ion

Aluminium is an integral member of the boron family in the periodic table, appearing like silver with a lower weight. The chemical representation of aluminium chloride is ‘Al’, and its atomic number is 13. When aluminium comes directly in contact with air, an oxygen

Bonding in coordination compounds, Chemistry, Class 12, Coordination Compounds, IIT JEECopper (3d10 4s¹) and chromium (3d5 4s¹) electron configurations This is because the energies of 3d and 4s orbitals are relatively near, and the energy of 3d orbitals decreases as you move across the row. The arrangement with more electrons in 3d orbitals has a lower energy for both chromium and copper. This is because

Bonding in coordination compounds, Chemistry, Class 12, Coordination Compounds, NEETIron(II) sulphate, also known as ferrous sulphate, refers to a group of salts with the formula FeSO4 xH2O. These compounds are most commonly known as heptahydrates (x = 7), but they are also known for a variety of other x values. The hydrated form is used in medicine to treat iron deficiency, as well as
Fluorine is the twenty-fourth most abundant element in the universe and the thirteenth most abundant element on Earth. As a result of its use in smelting metal ores to lower their melting points, the mineral was given its name from the Latin word fluo, which means “to flow.” Fluorite is the primary mineral source of
Fluorine has an electronic configuration of 2,7, which is a positive number. Fluorine is the ninth element in the periodic table, and it has a total of nine electrons. The first two electrons will be in the 1s orbital, which is the most stable. The 2s orbital is occupied by the next two electrons in
Gattermann formylation and Gattermann salicylaldehyde synthesis, the Gattermann reaction is a chemical reaction in which aromatic compounds are formulated by a mixture of hydrogen cyanide (HCN) and hydrogen chloride (HCl) in the presence of a Lewis acid catalyst, such as AlCl3. The reaction is named after the German chemist Ludwig Gattermann, and it is quite
