Answer #1

KMnO4 is an ionic crystal. So it will ionizes as K+ and MnO4- , so it is a polar molecule

We know that like dissolves like that means polar compounds disolve in polar solvents & non-polar compounds dissolve in non-polar solvents

Water is a polar solvent(strong dipole) so KMnO4 dissolve in water

Hexane non-polar organic solvent so KMnO4  insoluble in hexane & it has only vander Walls forces
Ethanol is also a polar solvent , KMnO4 also dissolves in ethanol But its solubility is more in water than that of ethanol.
