Synthetic detergents are cleaning agents that are synthesized and have chemical structures different from traditional soaps. Traditional soaps are salts of fatty acids, typically with a carboxylate head group (-COO-). Option C, CH$_3$(CH$_2$) $_{16}$COO$^{-}$ Na$^{+}$, is sodium stearate, which is a common example of a soap. Options A, B, and D represent synthetic detergents with different types of polar head groups: A is an anionic sulfate-based detergent, B is a cationic quaternary ammonium-based detergent, and D is a non-ionic polyoxyethylene-based detergent.
