Question

State the reason of the following 1) MnO is basic while Mn2O7 is acidic

​

Answer 1

MnO is basic in nature but Mn2O7 is acidic in Nature because:-

Generally, for transition metal oxides, the lowest oxidation state is the most basic, since it can donate lone pairs of electrons and function as a Lewis base. Higher oxidation states are short of electrons, meaning they can accept lone pairs and function as Lewis acids.

MnO has the lowest oxidation state, so it is the most basic and finally Mn2O7 (which is actually acidic)...
