Short Answer TypePb(NO3)2 on heating gives a brown gas which undergoes dimerization on cooling ? Identify the gas.
When coordination compound CoCl3.6NH3 is mixed with AgNO3, 3molesof AgCl is precipitated per mole of the compound. write
i) Structural formula of the complex
ii) IUPAC name of the complex
(i) Gas (A) is more soluble in water than Gas (B) at the same temperature which one of two gases will the higher value of KH (Henry's constant) and why ?
(ii)In non-ideal solution, what type of deviation shows the formation of maximum boiling azeotropes?
(i)According to Henry's law , at the constant temperature, the solubility of the gas in a liquid is directly proportional to the partial pressure of the gas on the surface of the liquid or solution. Gas B has a Higher value of KH and thus lower is the solubility of the gas.
p = KHx
(ii) Negative deviation from Raoult’s law
Write the structures of the following:
i) BrF3
ii) XeF4
Or
What happens when:
i) SO2 gas is passed through an aqueous solution Fe3+ salt ?
ii) XeF4 reacts with SbF5 ?
For a reaction: 
rate =k
i) Write the order and molecularity of this reaction.
ii) Write the unit of k.
a) For the complex [Fe(H2O)6]3+, write the hybridization,magnetic character and spin of the complex.(At.number: Fe=26).
b) Draw one of the geometrical isomers of the complex [Pt(en)2Cl2]2+ which is optically inactive.
Give reasons:
i) SO2 is reducing while TeO2 is an oxidizing agent.
ii) Nitrogen does not form pentahalide.
iii) ICl is more reactive than I2
Calculate the boiling point of the solution when 4g of MgSO4 (M =120 g mol-1) was dissolved in 100g of water,assuming MgSO4 undergoes complete ionization.
(Kb for water =0.52 K kg mol-1)
