Soaps consist of compounds such as sodium stearate,CH3(CH2)16COO-Na+ , that have both hydrophobic and hydrophilic parts. Consider the hydrocarbon part of sodiumstearate to be the “tail” and the charged part to be the“head.”(a) Which part of sodium stearate, head or tail, is more likelyto be solvated by water?(b) Grease is a complex mixture of (mostly) hydrophobiccompounds. Which part of sodium stearate, head or tail,is most likely to bind to grease?(c) If you have large deposits of grease that you want towash away with water, you can see that adding sodiumstearate will help you produce an emulsion. What intermolecularinteractions are responsible for this?

Question
Soaps consist of compounds such as sodium stearate,
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.”
(a) Which part of sodium stearate, head or tail, is more likely
to be solvated by water?
(b) Grease is a complex mixture of (mostly) hydrophobic
compounds. Which part of sodium stearate, head or tail,
is most likely to bind to grease?
(c) If you have large deposits of grease that you want to
wash away with water, you can see that adding sodium
stearate will help you produce an emulsion. What intermolecular
interactions are responsible for this?
