Dear rohit,

The thermal stability and the bond energies decrease from Hp to HjPo gradually. The order is H20 > H2S > H2Se > H2Te > H2Po.

 

MnO behaves as a basic anhydride, MnO2 is amphoteric, and Mn2O7 is acidic.

We are all IITians and here to help you in your IIT JEE preparation.

All the best.
