Manganese dioxide (MnO2) is considered a polar compound due to the difference in electronegativity between manganese (Mn) and oxygen (O), which leads to an uneven distribution of electron density. This results in a dipole moment, making it polar. Additionally, the molecular structure and the arrangement of oxygen atoms around the manganese contribute to its polar characteristics.
Manganese dioxide is non-homogeneous catalyst.

It is non-polar
Polar molecules reacts with polar molecules and non-polar molecules react with non-polar molecules.

polar
Water is polar while oils are non-polar. Molecules that are polar will mix with other polar molecules, and non-polar molecules will mix with other non-polar molecules. Polar and non-polar molecules will not mix.
