Q. Describe Linkage Isomerism?
Some ligands can coordinate to the metal through different donor ato...s present in the ligand. They are called ambidentate ligands and they can produce linkage isomer with a metal ion. Isomerism of this kind is shown by the isomeric pair: [(NH3) CoNo2]2+ yellow brown known as nitro compound and : [(NH3) CoNo2]2+red coloured isomer known as nitito complex. Other example is: Compounds with ligands like SCN which can bind through S or N donor atom, or sulphoxides, R2S0, which may combine through S or 0.
Effects of substituents on the acidity of phenols: Existence of electron attracting group, (for example -NO 2 , -X, - NR + 3 , -CN, -CHO, -COOH) on the benzene ring increases
Coordination complexes are so pervasive that the structure and reactions are defined in many ways, sometimes confusingly. The atom within a ligand that is bonded to the central ato
How many KCal of heat are liberated when 48.0 grams of iron are burned to form Fe2O3 at standard state conditions? (Change of Hf^0 of Fe2O3 is -197 kCal/Mole )
A transition metal X has a configuration [Ar] 3d 4 in its +3 oxidation state. Its atomic number is: (1) 25 (2) 26 (3) 22 (4) 19 Ans: 25
The f-block elements contains of two series of inner transition elements i.e. lanthanoids (the fourteen elements subsequent lanthanum) and actinoids (the fourteen elements subseque
The angle among the lines joining the nuclei of the bonded atom with a central atom is known as bond angle.
