Soap molecules have dual properties; one end of the molecule is hydrophobic and the other is hydrophilic. What are the intermolecular forces that lead to the hyrophobic and hydrophilic properties? Be specific!
Homework Answers
General formula of soap is RCOO-Na+ . Hydrocarbon part is hydrophobic ( water repellent) while COO- is hydrophilic ( water loving) .
Interaction between hydrophilic part is Dipole - Dipole , Hydrogen bonding or ionic interactions
while interaction between hydrophobic part is London
dispersion forces.
