Sоаps cоnsist оf compounds such аs sodium steаrate, CH3(CH2)16COO-Na+, that have both hydrophobic and hydrophilic parts. Consider the hydrocarbon part of sodium stearate to be the "tail" and the charged part to be the "head." Which part, the tail or the head, would be more likely involved in (1) the hydration by water? (2) dissolving grease which is mostly a hydrophobic compound?
