2621) agree with swaraj
2) i am getting less than 20% . plz someone try.
1) what is the hybridisation state of central atom in the cationic part of the solid form of XeF6?
(A) sp3
(B) sp3d2
(C) sp3d
(D) dsp2
[please don't google. i have the answer but didn't get it myself..so jus wanted to check how many of you know how to do such typical inorg questions :) ]
2) A mixture of H2SO4 and H2C2O4 and some iner impurity weighing 3.185 g was dissolved in water and solution made upto 1 L. 10mL of this solution required 3mL of 0.1 N NaOH solution for complete neutralisation . In another experiment 100mL of the same solution in hot condition required 4mL of 0.02 M kMnO4 solution for complete reaction .
The weight % of H2SO4 in the mixture was;
(A) 80%
(B) 60%
(C) 40%
(D) 20%

211)according to me should be (b).
Just like PCL5 exists as PCL4+ & PCL6- to make the structure more symmetric.Similarly XeF6 should exist as XeF5+[octahedral] and XeF7-[cubic structure] to make the structure stabler.
71I had asked recent question regarding the PBr5 :P answered by Aditya.
262262maybe to provide some activation energy or to increase the rate.
71I don't think. On heating the oxalic acid may give off CO2.
