Select the complex that involves outer hybridization of central metal ion.

A complex containing Mn²⁺ and Br^– ion was found to have a magnetic moment of 5.92 BM. The probable formula and geometry of the complex is most likely to be :

A solution of ‘X’ containing 0.02 mole of ‘X’ per litre is mixed with another solution, a solution of ‘Y’ containing 0.02 mole of ‘Y’ per litre. 

     1 L of mixture solution + AgBO₃ → ‘A’ ↓ 

     1 L of mixture solution + Excess BaCl₂ → ‘B’↓  

If  ‘X’ is [Co(NH₃)₅SO₄]Br, and    

     ‘Y’ is [Co(NH₃)₅Br]SO₄,

then the number of moles of ‘A’ and ‘B’ obtained are, respectively

This type of splitting of d-orbitals occurs in the formation of

Which is not a π-acceptor ligand?

A complex of a certain metal ion has a magnetic moment of 4.90 B.M. Another complex of the same metal ion in the same oxidation state has a zero magnetic moment. Which of the following could be the central metal ion in the two complexes?

Which of the following is most acidic aqua ion?

We get a copper complex with ammonia having the formula [Cu(NH₃)₄]²⁺only in alkaline solution and not in acidic solution. It can be explained on the basis of the fact that :
