Fat contains mostly nonpolar bonds. These will not dissolve in water because water contains polar bonds. It will dissolve in alcohol because alcohols have both polar and nonpolar bonds. Oils have mostly nonpolar bonds so the fat will dissolve.
NaHCO3 is an ionic material. It will dissolve in water due to the polar bonds of the water interacting with the ions. There are not enough polar bonds present in the alcohol for the material to dissolve, and it will not dissolve in the nonpolar oil since it requires charges to be separated.
