Yes Because in KMnO4 Mn is reduced from an oxidizing state of 7 to 5, when a species are reduced, it oxidizes... the case is similar with dichromate

There are a plethora of oxidizing brokers which will properly be utilized to result selective or non-selective oxidations,,,chromic oxide, potassium permanganate, potassium dichromate, pyridine sulfur trioxide complicated, pyridinium dichromate, silver oxide, mercuric oxide, Cu+2, and particularly some, many, greater .

Yes, check out their standard electrode potential. their reduction potentials being positive indicates they are strong oxidising agent. KMnO4 is a stronger oxidising agent of the two.

In acidic solution (as they normally are):
(MnO4)- + 8H+ + 5e- -----> Mn2+ + 4H2O E0 = +1.52V
(Cr2O7)2- + 14H+ + 6e- -----> 2Cr3+ + 7H2O E0 = +1.33V
Thus they are both good oxidising agents, but KMnO4 in acidic solution is slightly more powerful.
