Many theories have been put forth to explain the nature of bonding in co-ordination compounds:- What is the geometry of the [ N i ( C N ) 4 ] 2 − . complex?

Many theories have been put forth to explain the nature of bonding in co-ordination compounds:- On the basis of valence bond theory account for the diamagnetic behaviour of [Ni(CN)_4]^(2-) .

Many theories have been put forth to explain the nature of bonding in coordination compounds.Arrange the following ligands in the increasing order of their field strengths(as in the spectro chemical series) Cl^-,CO,H_2O,OH^- .

Write down the IUPAC name for each of the following complexes and indicate the oxidation state, electronic configuration and coordination number. Also give stereochemistry and magnetic moment of the complex.. i) K[Cr(H_2 O)_2(C_2 O_4)_2] 3H_2 O ii) [CrCl_3(Py)]_3 iii) K_4[Mn(CN)_6] iv) [Co(NH_3)_5 Cl] Cl_2 . v) Cs[FeCl_4]

Read the following and answer the questions given below. 1,2,3,4….are natural numbers or counting numbers. The sum of first 4 numbers is 1+2+3+4=(1+4)+(2+3) = 5+5 = 5xx2 =(4+1)+4/2 We can make pairs as given above and can establish a formula to find the sum of first n natural numbers as sum = (1+n)xxn/2 What is the number at the right and of 10^th line 1 2 3 4 5 6 7 8 9 10 .............

Two hints regarding a hydrocarbon is given below. * It consists of 4 carbon atom * The general formula of the series which indicates is C_(n)H_(2n+2) a) Write the molecular formula of the compound b) Give the structure of the compound. c) What will be the molecular formula of the hydrocarbon with the same number of carbon atoms and having a double bond d) Write the structure of the cyclic hydrocarbon with the same number of carbon atoms.

Valance Bond theory(VBT) can explain the magnetic behaviour and shape of complexes Using VBT explain the diamagnetism and square planar shape of Ni(CN)_4]^2-
