Q. Example of octahedral complexes?
Let us now turn our attention to the complexes having transition metal ion with d2 or d3 electrons. With these configurations, there are enough of vacant orbitals available to accept the pairs of elements from four or six ligands to form tetrahedral, square planar or octahedral compound. The magnetic moment of the complex will be the same as free ion value as shown in the diagram given below:
When the number of d electrons is greater than three and up to six as in d2, d6 systems, there is still a possibility of forming octahedral complexes using d2sp3 hybridised orbitals by forcing some of the electrons to pair up.
Number of unpaired electrons in Mn 4+ is: (1) 3 (2) 5 (3) 6 (4) 4 Ans: 3
Why cyclo propane is more stable than cyclohexane
CH 3 COOH ( ethanoic acid) + NH 3 ------------ > CH 3 COONH 4 + (HEAT) ---------- > CH 3 CONH 2 (methyleamine) + H 2 O
Fundamentals of Acids and Bases Bronsted-Lowry theory: A Bronsted acid is a (proton) + donor, whilst a Brønsted base is a proton acceptor. An acid-base reaction involves t
Reaction involving cleavage of with removal of 'H' as proton Alcohols are stronger acids as compared to terminal acetylene but are not acidic enough to react along with aqueous
when a 0.800g sample of cacl2 is dissolved in 9.85g of water in a microscale calorimeter, the temperature of the solution rose from 23.4 to 35.8
In order to determine the standard electrode potential of an electrode, the electrode in standard conditions is connected to standard hydrogen electrode (SHE) to constitute a cell.
how was the magnitude of electric charge concluded?
Electro refining of Copper • Electrolyte - Aqueous copper sulphate solution (acidified) • Cathode - Pure copper metal (thin rod) • Anode - Impure copper metal (thick block) • Disso
Correct set of four quantum numbers for valence electron of rubidium (Z = 37) is: (1) 5,0,0,+1/2 (2) 5, 1,0,+1/2 (3) 5,1,1,+1/2
