CH3CHF2 is polar. If you draw the structure of the compound, you'll realize one C has 3 H ligands while the other C has 1 H ligand and 2 F ligands. As we know, polar=asymmetrical. Therefore, since both "tetrahedrals" are different, it is asymmetrical.
CH3F is polar. There are differences in electronegativity which are not canceled by the molecules tetrahedral shape.
