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.
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%

71I had asked recent question regarding the PBr5 :P answered by Aditya.
2621) agree with swaraj
2) i am getting less than 20% . plz someone try.
262maybe to provide some activation energy or to increase the rate.
71I don't think. On heating the oxalic acid may give off CO2.
