1Perhydrol is toh hydrogen peroxide.
1.What exactly is meant by BACK BONDING ?
2.What is Perhydrol ?
3.PBr4 and PI4 doesnot exist according to my theory book and reason given is that Pb4+ is a strong oxidant and Br- and I- are strong reductants [ and so Pb4+ cant exist for long ] ..which is TRUE..but then what about PF4 and PCl4 ???
4.What is a MORDANT ?
5.Does Nitrogen have the maximum/minimum catenation ability in Gp-15..why / why nt ?
6.Explain the following trend in THERMAL STABILITY AND ACIDIC CHARACTER :
HCl03 > HBr03 > HI03 ?

1ya..i know its related to H2O2..but there is some relation based on molarity or something ? [ like volume strength ]
1Mordant, I think is a colouring material........yeah, it is a dye. A complex compound.
395. Nitrogen does catenate but to a lesser extent. We've discussed this one before js. An example of nitrogen catenation is N2. But the lack of d-orbitals gives phosphorus the top spot for catenation in group 15.
4. A mordant is something used to dye fabrics such that a complex is formed which attaches to the fabric. It is a metal ion(polyvalent). The complex so formed is colloidal in nature.
1Thanks guys but 3 important QUESTIONS are left..pls try to reply to them also..

1For back bonding one, this might be of some use

I found this one tuff!!
111 reason for the 3rd qsn maybe is that Bromine and Iodine are larger in size compared to Fluorine and Chlorine.
So sterically PBr4 and PI4 are unstable.

1ya Soumik..but how can figure out the other two compounds of F an Cl as they have so much reducing power..?...[12]
